Question

in triangle PQR, PQ = QR and QPR = 80° . Find the remaining angle.​

Answer 1

Step-by-step explanation:

hope it helps

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
