we will use formula
where
theta is angle
n is number of sides
we are given
n=15
we can plug it
now, we can solve for theta
so,
option-D.........Answer
Answer:
Surface Area = 86 cm^2
Step-by-step explanation:
Given:
Triangle,
b = 8 cm
h = 9 cm
Rectangle,
l = 10 cm
w = 5 cm
To Find:
Surface Area = ?
Solution:
Surface Area = b x h /2 + l x w
Surface Area = 8 x 9 / 2 + 10 x 5
Surface Area = 4 x 9 + 50
Surface Area = 36 + 50
Therefore, Surface Area = 86 cm^2
PLZ MARK ME AS BRAINLIEST!!!
The figure/drawing isn't needed to answer this question.
The question tells us ABCD ~ WXYZ, which means trapezoid ABCD is similar to WXYZ.
Point A corresponds to point W, B corresponds with X, C corresponds with Y, and D corresponds with Z (first, second, third, and last letters correspond with each other according to the similarity statement).
Now let's check each answer choice and see which applies to these similar trapezoids:
- Since point B corresponds with point X and the trapezoids are similar, they must be congruent angles. Thus, the first choice is correct.
- Point Y does not correspond with point A. Thus, it is possible the angles are not congruent. The second choice is incorrect.
- Point A corresponds with W and B corresponds with X. Thus, line segment AB will be similar to line segment WX. However, they are not equal. Thus, the third choice is incorrect.
- There's an equal sign in this choice, too, just like the last, and the two segments are corresponding line segments. Thus, the fourth choice is incorrect.
- This looks like the third choice, but with a similarity symbol instead of an equal sign. Now, the statement is true and the fifth choice is correct.
- This looks like the fourth choice but with a similarity instead of an equal sign. Now, the statement is true and the sixth choice is correct.

Answer:
what is it over?
Step-by-step explanation:
you have to be more specific
Answer:
A
Step-by-step explanation:
This is because vertical angles are always congruent, they cross diagonally which makes them equal to each other.
