Question

In a triangle PQR if angle QPR=80 degree and PQ=
PR then find angle R and angle Q

Answer 1

Given, QPR is 80 degrees
and PQ=PR
let the other two angles be x,x because it is an isosceles triangle
by triangle sum property
80+x+x=180
2x+80=180
2x=100
x=50
therefore angle R and angle Q are 50 degrees

Answer 2

Given - Angle QPR

Find - Angle R and Angle Q

Solution - As per the given information, the triangle is isosceles triangle. So, angle R and Angle Q will be same. Let these angles be x.

x + x + 80 = 180

Performing addition

2x + 80 = 180

Shifting 80 to Right Hand Side

2x = 180 - 80

Performing subtraction

2x = 100

Shifting 2 to Right Hand Side

x = 100/2

Performing division

x = 50°

So, the angle R and Angle Q is 50°.
