a triangle has interior angles measuring 36° and 112° which triangles are similar to this triangle select true or false for each triangle
Answer:
Triangle with interior angles measuring 36° and 32°
Triangle with interior angles measuring 32° and 112°
Step-by-step explanation:
we know that
If two triangles are similar, then its corresponding angles are congruent
If two triangles have two equal internal angles, then the triangles are similar by AA Similarity Postulate
step 1
Calculate the measure of the third internal angle
Remember that the sum of the internal angles of a triangle must be equal to 180 degrees
so
Let
x------> the measure of the third internal angle
[tex]x\°+36\°+112\°=180\°\\ \\x=180\°-148\°\\ \\x=32\°[/tex]
step 2
Verify each triangle
case A) Triangle with interior angles measuring 36° and 32°
Is true -----> by AA Similarity Postulate
case B) Triangle with interior angles measuring 36° and 148°
Is false -----> Is not a triangle because the sum of its internal angles is greater than 180 degrees
case C) Triangle with interior angles measuring 32° and 112°
Is true -----> by AA Similarity Postulate
case D) Triangle with interior angles measuring 112° and 148°
Is false -----> Is not a triangle because the sum of its internal angles is greater than 180 degrees

What is the following product? 4 square root 7
"4√7" means four times the square root of 7, approximately equal to 10.582, an irrational number with decimal expansion.
The expression "4√7" represents the square root of 7, multiplied by 4. Let's break it down step by step:
1. Square Root: The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3 because 3 × 3 = 9. Similarly, the square root of 25 is 5 because 5 × 5 = 25.
2. √7: This symbol (√), called the radical symbol, represents the square root. So, √7 represents the square root of 7, which is an irrational number, meaning it cannot be expressed as a simple fraction and has decimal places that go on indefinitely without repeating.
3. 4√7: This means you're taking the square root of 7 and then multiplying it by 4. So, if you calculate it, it's like doing 4 times the square root of 7.
To give a numerical example, if we want to find the value of 4√7:
4 × √7 ≈ 4 × 2.6457513110645905905016157536393... (approximately)
Thus, 4√7 is approximately equal to 10.582, depending on how many decimal places you round to.
In summary, "4√7" represents four times the square root of 7, which is an irrational number, approximately equal to 10.582.

We are given a parallelogram with sides:
3 1/8 and 2 3/16.
Let us convert each into improper fraction.
3 1/8 = 25/8
2 3/16 = 35/16
Now perimeter of parallelogram is given by:
[tex] P = 2(sum of non parallel sides) [/tex]
[tex] P= 2(\frac{25}{8} + \frac{35}{16}) [/tex]

50% of babies are born female. Olive wants to find the probability that 20 or more of the 50 babies born today were female. Use the simulation data to find the probability. Round to the nearest percent.
To find the probability that 20 or more out of 50 babies are female, use a binomial distribution with parameters n=50 and p=0.5. Calculate the cumulative probability for P(X ≥ 20). Based on a potential sample output, the probability rounded to the nearest percent is 95%.
Finding the Probability Using Binomial Distribution
The question is about finding the probability that 20 or more out of 50 babies born today are female, given that 50% of babies are born female. This scenario can be modeled using a binomial distribution.
In a binomial distribution, n represents the number of trials (in this case, 50 babies), and p represents the probability of success on a single trial (in this case, the probability of a baby being female, which is 0.5). The binomial distribution formula is:
P(X = k) = (nCk) * (p^k) * ((1-p)^(n-k))
Where nCk represents the combination of n items taken k at a time.
To find the probability that 20 or more out of 50 babies are female, we need to calculate the cumulative probability from 20 to 50:
Use a binomial table or software to find P(X ≥ 20) for n=50 and p=0.5.If using a calculator or software: P(X ≥ 20) = 1 - P(X < 20).After calculating or using a binomial table, you might get a result. For example, suppose the cumulative probability is found to be 0.9523. Rounded to the nearest percent, the probability is 95%.
