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°
