Answer:

∠a=80

∠b=50

Step-by-step explanation:

∠a and 100 are on a straight line. Therefore they are supplementary, and add to 180 degrees. So, we can say that:

∠a+100=180

To solve, subtract 100 from both sides. This will leave ∠a by itself.

∠a +100-100=180-100

∠a=80

The angles in a triangle must add to 180 degrees. Therefore,

∠a + ∠b + 50= 180

We know ∠a is 80, so we can substitute that in

80+ ∠b +50 =180

∠b+80+50=180

Combine like terms

∠b+(80+50)=180

∠b+130=180

To solve, subtract 130 from both sides. This will leave ∠b by itself.

∠b+130-130=180-130

∠b=50

Answer:

∠a = 80° and ∠b = 50°

Step-by-step explanation:

Look at angle a. Angle a and 100 both lie on the same line, which means they are supplementary and add up to 180. Then we can write: m∠a + 100 = 180. To solve this for a, we simply subtract 100 from both sides:

m∠a = 80°

Now, look at the triangle. All the angles in a triangle add up to 180, so we have the equation: m∠b + 80 + 50 = 180. Solve for b by subtracting 80 and 50 from both sides: m∠b = 50°.

Thus, ∠a = 80° and ∠b = 50°.

Answer:

54°

Step-by-step explanation:

Complementary angles sum to 90°, thus

∠ Z2 = 90° - 36° = 54°

Area of blank is 326.56m²

Step-by-step explanation:

For a better and pictorial understanding of this problem please see attached for your reference.

Given data

Let the flower bed be the small circle with diameter d= 22m

Radius of small circle = 22/2=11m

Let the side walk be the big circle with diameter D= 4+4+22=30m

Radius of big circle =30/2 = 15m

We know that the area of circle

A1=πr²

Hence area of flower bed

A1=3.14*11²

A1= 379.94m²

Also area of side Walk

A2= πr²

A2= 3.14*15²

A2= 706.5m²

Area of blank

A3= area of side walk - area of flower bed

A3= A2-A1

A3= 706.5-379.94

A3= 326.56m²

Answer:

I can conclude that Sally went down the slide. I used deductive reasoning to get my answer. Sally said that if it was sunny, she would go to the park. She also said that if she does go to the park, she will go down the slide. Since Sally did go to the park, I know that she did go down the slide. Based on the information I have, I can use deductive reasoning to get to my answer.

Step-by-step explanation:

Based on Sally's conditions and the law of syllogism, since it's sunny, we can conclude Sally will go to the park and go down the slide.

From Sally's statements, since the next day is sunny, we can conclude that Sally will go to the park and go down the slide. This conclusion is based on the law of syllogism in logic, which allows us to link two related conditional statements. In this scenario, the first conditional statement is 'If it's sunny, I will go to the park', and the second is 'When I go to the park, I go down the slide'. As it's sunny, the law of syllogism lets us link these conditions to infer that Sally will indeed go down the slide at the park.

Answer:

Step-by-step explanation:

The sum of the angles of a triangle is 180

A +B +C = 180

90 +4x+ 7x-20 =180

Combine like terms

70+ 11x = 180

Subtract 70 from each side

70-70+11x = 180-70

11x=110

Divide each side by 11

11x/11= 110/11

x = 10

Step-by-step explanation:

Some of the population may not have access to other types of phones.

The policy of conducting a portion of surveys on mobile phones helps address the source of bias wherein some people may not have access to other types of phones. By including mobile phones, pollsters can have a more representative sample, reflecting the population more accurately. However, this does not guarantee participation or comprehension of survey questions.

The policy of political pollsters to conduct a percentage of their telephone interviews by calling mobile phones best addresses the source of bias that some of the population may not have access to other types of phones. This is reflective of a shift in communication behaviors wherein a significant percentage of the population exclusively uses mobile phones, especially among younger and middle-aged adults. This phenomenon could lead to a selection bias if only landline numbers were used, as the respondents would likely skew toward older individuals and those who are at home more often.

By integrating mobile phones in their survey methods, the pollsters are able to get a more representative sample that more accurately reflects the entire population. For instance, random-digit-dialing is a technique that allows pollsters to include respondents who have unlisted or mobile numbers. Similarly, geographically-based screenings can be employed to avoid regional bias.

However, it is important to note that including mobile phones in the survey does not address other kinds of bias. For instance, reaching out to potential respondents does not guarantee their participation, and it does not mean that the respondents would fully understand the wording of the survey questions. It only helps in achieving a more demographically reflective sample.

Answer:

Step-by-step explanation:

Based on the proportion of Chinese food menus Maura has already received (3 out of 15),we would expect her to receive approximately 4 Chinese food menus in the next batch of 20 menus.

To solve this, we look at the probability of Maura receiving a Chinese food menu by using the proportion of Chinese menus she has already received.

This initial probability is 3 out of 15, which simplifies to 1 out of 5. Therefore, we'd expect to receive the same proportion from the next set of menus.

To predict the number of Chinese food menus in the next 20, we multiply the total number of new menus by the probability of each being Chinese:

20 menus * (1/5 probability of Chinese) = 4 Chinese menus

Answer:

-4.4

Step-by-step explanation:

In order to do this, we need to move the variables to one side, and the numerical values to the other.

-20-7x=-2x+2

We can do this by adding 7x to both sides first

-20=5x+2

Now we can subtract 2 from both sides.

-22=5x

Next, we can divide each side by 5.

x=-22/5

Then we simplify the fraction

x=-4.4

Answer:

x = -4.4

or

x = 22/-5

Step-by-step explanation:

-20-7x = -2x+2

-7x = -2x+20+2

2x-7x = 22

-5x = 22

x/-5 = 22/-5

x = -4.4

or

x = 22/-5

Answer:

when they have equal sides and the exact shape and the same angle measures. they have tobe the same size.

Step-by-step explanation:

For example, when you have a square with sides 3 cm, then you compare it with the exact copy of the square. These squares are congruent. Two figures are congruent if and only if they have the exact same shape and the exact same size. If the corresponding sides of two figures with the same shape have the same length, then the two figures are congruent.

The figures that appear be congruent have all sides as equal and in the exact shape and can measure the same angles. They have the same size.

The instruments is those figures and objects that have the same size and shape. The meaning of the work congruent is that they are identical to each other and in an agreement and harmony

Step-by-step explanation:

Answer:

The value of angle A is 19.415 degrees.

Explanation:

Let's recalculate using the Law of Cosines to find the measure of angle[tex]\(A\)[/tex] in triangle [tex]\(ABC\)[/tex].

Given:

- [tex]\(a = 3.4\)[/tex] cm

- [tex]\(b = 7.9\)[/tex] cm

- [tex]\(c = 5.3\)[/tex] cm

We want to find angle [tex]\(A\)[/tex]. To use the Law of Cosines, we first need to find angle [tex]\(C\)[/tex]. We can use the Law of Cosines again:

[tex]\[ a^2 = b^2 + c^2 - 2bc \cos(A) \][/tex]

[tex]\[ (3.4)^2 = (7.9)^2 + (5.3)^2 - 2(7.9)(5.3) \cos(A) \][/tex]

[tex]\[ 11.56 = 62.41 + 28.09 - 83.54 \cos(A) \][/tex]

[tex]\[ 11.56 = 90.5 - 83.54 \cos(A) \][/tex]

[tex]\[ 83.54 \cos(A) = 90.5 - 11.56 \][/tex]

[tex]\[ 83.54 \cos(A) = 78.94 \][/tex]

[tex]\[ \cos(A) = \frac{78.94}{83.54} \][/tex]

[tex]\[ \cos(A) \approx 0.944 \][/tex]

Now, to find the measure of angle \(A\), we take the inverse cosine (cos⁻¹) of 0.944:

[tex]\[ A \approx \cos^{-1}(0.944) \][/tex]

[tex]\[ A \approx 19.415° \][/tex]
