Question

In angle PQR : angleP = 30 PQ = PR then find measurement of angleQ and angle R. class 7​

Answer 1

Answer:

75°

Step-by-step explanation:

angle P = 30°

PQ = PR

so, angle Q = angle R= x

x+x +30° = 180°

2x = 180° -30°

x= 150°/2

x=75°

Answer 2

Answer:

In angle PQR : angleP = 30 PQ = PR then find measurement of angleQ and angle R.

x +x +30=180

2x + 30=180

2x= 180-30

2x=150

x=150÷2

x=75
