You are asked for an angle. You need to use the inverse sine.

The answer is about 30 degrees. See below.

Step-by-step explanation:

Sin(y) = opposite / hypotenuse

opposite = 9cm

hypotenuse = 17 cm

Sin(y) = 9/17

y = sin-1(9/17)

y = sin-1(31.97) degrees.

To the nearest 1/10 of a degree, it would be

y = 32.0 degrees.

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
