 This is a cyclic quadrilateral and opposite angles add up to 180 degrees. Therefore is is 180 - 90 = 90 degrees

Answer:

D) 90°

Step-by-step explanation:

Here we are given a cyclical quadrilateral.

We have to use the property of quadrilateral to find the value p.

i) In a quadrilateral adjacent angles add upto 180 degrees.

ii) Opposite angles add upto 180 degrees.

Here the following angles are the opposite to each other.

∠p = 90°

∠q = 58°

The opposite angles add upto 180 degrees.

∠p + 90° = 180

Subtract 90° on both sides, we get

∠p + 90° - 90° = 180° - 90°

∠p = 90°

The answer is D) 90°
