Question

please answer my question​

Answer 1

Answer:

Measure of angle P is 20°.

Step-by-step explanation:

In isosceles triangle:- PQ= PR

So, angle Q and angle R are equal (Angles opposite to equal sides are also equal)

Angle Q = 80° (Given)

So, angle R = 80°

Angle sum property of a triangle:-

Angle P + angle Q + angle R = 180°

Angle P + 80° + 80° = 180°

Angle P = 180° - 160°

Angle P = 20°

Therefore, measure of angle P is 20°.
