What is the area of this face?
A.150in2
B.100in2
C.400in2
D.200in2

200 in squared.

Step-by-step explanation:

The top face has a height of 10, it also has a side length of 10. 5 plus 5 equals 10. These faces are squares, so the sides are equal. In this case, they 10 by 10. To find the of the face you do 10 times 10 times 2 because there are 2 figures, or you can find the area of one (100) and the area of the other (100) and add the areas up to get the area of the face. Hope this helps!

Step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
