Question

In a triangle PQR, angle QPR=80degrees and PQ=PR ... WRITE THE VALUE OF angle R and angle Q

Answer 1

Answer:

50°

Step-by-step explanation:

Since PQ=PR, and one angle is 80°, NOT 60°, the triangle is isosceles. So, Angle Q and Angle R are same. Let it be x.

So, 80+ 2x= 180°

2x= 100°

x= 50°
