Out of 25 students taking a midterm psychology exam, 17 answered the first of two bonus questions, 12 answered the second bonus question, and 1 didn't bother with either one. Round your answer to the nearest percent.

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

this is answer of 144 cubic meters
