Question

(a) 70
(0) 90
-. In a triangle PQR if ZQPR = 80° and PQ = PR, then ZR and ZQ are :
(a) 80°, 70°
(b) 80°, 80°
(c) 70°, 80°
(d) 50°, 50°​

Answer 1

Answer:

(d) 50°,50°

Step-by-step explanation:

we have given angle PQR = 80°

and PQ = PR

then, by angle sum property,

angle PQR + angle PRQ + angle QPR = 180°

angle PQR = angle PRQ = x ( As PQ = PR)

so,

2x + angle QPR = 180°

2x + 80° = 180°

2x = 100°

x = 50°

therefore,

angle PQR = angle PRQ = 50°
