The answer is choice D) Two rays that share the same endpoint
======================================
Here's a full breakdown of the four choices
A. False. If the ray and line aren't touching, then an angle can't be formed.
B. False. Parallel lines never cross. The same issue as before (in part A) comes up.
C. False. Again the rays need to meet up somehow.
D. True. If you have two rays that share the same endpoint, then they form an angle. Think of it like a pair of scissors. Each blade is a ray. The blades are joined at a common node to allow the blades to swing open or closed. You could have an angle formed by line segments or lines, but they would have to intersect in some way.
Option D. two rays that share the same endpoint, is correct.
An angle is formed by:
A. any ray and any line
B. parallel lines
C. any two rays
D. two rays that share the same endpoint
The angle can be defined as the one line inclined over other line.
When the line as same end points and
one of the line is inclined over other by some measure called as angle.
Thus the option D two rays that share the same endpoint is correct

Reflectional symmetry is the quality a design has if it maintains _____ when it is reflected across an axis or line of symmetry. A. some characteristics B. all characteristics C. no characteristics
The correct answer would be B, all characteristics. Reflectional Symmetry is when an object is divided into halve in which to completely identical pieces are left.
(B) All characteristics.
Reflection symmetry:In mathematics, symmetry with regard to a reflection is known as reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry. In other words, a figure with reflectional symmetry does not alter when it is reflected.There is a symmetry line or axis in 2D and a symmetry plane in 3D. A mirror-symmetric object or figure is one that is identical to its changed counterpart. In conclusion, the shape is divided in two by a line of symmetry, and both parts should be the same.Therefore, the correct option to fill the blank is (B) All characteristics.

Solve the equation. Check your solution, if possible
[tex]4(3q - 2) = 16q[/tex]
Hey there!!
Given equation :
... 4 ( 3q - 2 ) = 16q
... 12q - 8 = 16q
Subtract by 12q on both sides
... -8 = 4q
Divide by 4 on both sides
... -8 / 4 = q
... q = -2
Given equation :
4 ( 3q - 2 ) = 16q
Substitute the value of -2 in place of q
... 4 ( -6 -2 ) = 16 × -2
... 4 ( -8 ) = -32
... -32 = -32
∴ Hence proved
Hope my answer helps!!
A rope is used to anchor a boat to the shore. The angle of depression from the boat to the water is 40° . The height of the boat above the water is 25.17 feet. What is the length of the rope that is anchoring the boat to the shore?
Final answer:
To find the length of the rope anchoring the boat to the shore, use the tangent function with the angle of depression and the height of the boat above the water.
Explanation:
To find the length of the rope anchoring the boat to the shore, we can use trigonometry. The angle of depression from the boat to the water is 40° and the height of the boat above the water is 25.17 feet. We can use the tangent function to find the length of the rope. tan(40°) = opposite/adjacent. The height of the boat above the water is the opposite side and the length of the rope is the adjacent side. So, we have:
tan(40°) = 25.17/adjacent
Solving for the adjacent side, we get:
adjacent = 25.17 / tan(40°)
Using a calculator, we can evaluate this expression to find that the length of the rope is approximately 33.95 feet.
What is −13+2z=−56 Thanks
To solve the equation −13+2z=−56, we isolate z by first adding 13 to both sides, giving 2z=−43, and then dividing both sides by 2, resulting in z=−21.5.
Explanation:The student is asking for the solution to the linear equation −13 + 2z = −56. To solve for z, we need to perform two steps. First, add 13 to both sides of the equation to isolate the term with z on one side. This gives us 2z = −43. Next, we divide both sides by 2 to solve for z, which results in z = −21.5.

Find the slope of a mountain that descends 100 meters for every horizontal distance of 1,000 meters.
We are given: a mountain descends (getting down vertically) = 100 meter.
For getting down we would take it by a negative number so it would be -100 meter.
And every horizontal distance = 1,000 meter.
We know formula for slope is = Change in vertical distance/ Change in Horizontal distance.
Plugging values in formula of slope above, we get
Slope = -100/1000 = -1/10 or -0.1.
Therefore, we could say the slope of a mountain is [tex]-\frac{1}{10}\ or \ -0.1.[/tex]

yes 1/16
Step-by-step explanation:
One number is one-fifth of another number. The two numbers total 18. Find the numbers
Answer:
One number is 17 and the other is 85.
Step-by-step explanation:
Let the numbers be m and n. Let m = (1/5)n. Note that m+n = 18.
Substituting (1/5)n for m in the 2nd equation, we get (1/5)n + (5/5)n = 18. Multiplying all three terms by 5 to remove fractions, we get n + 5 = 90, so that n = 85. m is (1/5) of 85, or m = 17.
Final answer:
The two numbers in question are 15 and 3. To find them, establish a variable for the larger number, set up an equation based on the given ratio and sum, solve for the variable, and divide by five to get the smaller number.
Explanation:
The student wishes to find two numbers where one number is one-fifth of the other and their sum is 18. Let's denote the larger number as x and the smaller number as one-fifth of x, or x/5. The equation representing their sum is x + (x/5) = 18. To solve for x, we first find a common denominator, which is 5, and rewrite the equation as 5x/5 + x/5 = 18. Combining like terms gives us 6x/5 = 18. Multiplying both sides by 5/6, we get x = (18 × 5) / 6. Simplifying this gives x = 15. We then calculate x/5 to find the smaller number, yielding 3. Therefore, the larger number is 15 and the smaller number is 3.

Which of the following rational numbers is equal to 3 point 4 with bar over 4? 31 over 9, 32 over 9, 33 over 9, 34 over 9
ANSWER
[tex]3.\bar4 =\frac{31}{9}[/tex]
EXPLANATION.
Let [tex]y=3.\bar4---(1)[/tex]
This is a recurring decimal. So we need to multiply by 10 to form a new equation that will cater for the recurring but when subtracted.
Multiply (1) by 10 to obtain,
[tex]10y=34.\bar4---(2)[/tex]
Equation (2) -equation (1) gives;
[tex]9y=31[/tex]
[tex]\Rightarrow y=\frac{31}{9}[/tex]
Hence the correct answer is A.
The legs of a right triangle measure 5 inches and 7 inches. If theta is the angle between the 7 inch leg and the hypotenuse, sin theta = ___
Answer:
sin (θ) = 0,58
Step-by-step explanation:
The formula for sin (θ) is:
sin (θ) = (opposite side)/hypotenuse
The opposite side to the θ angle is the one that measures 5 inches, but we don’t know the measure of the hypotenuse. The Pythagoras theorem gives us the following formula:
side 1²+ side 2²= hypotenuse²
Then,
5²+7²=74
√74= 8,60 inches; this is the measure for the hypotenuse.
Replacing this value in the formula for sine:
sin (θ) = 5/8,60 = 0,58

find x if a =13 and C = 47 need help
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you dont have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)
