Question

Find the unknown angle in the following figure​

Answer 1

P+Q+R=180

GIVEN PR=PQ

OR R=Q=55°

SO

Q=55°

Now

P+55°+55°=180°

P+110°=180°

P=180°-110°=70°

P=70°

HOPE THIS ANSWERS YOUR QUESTION

Answer 2

Answer:

angle P +angle Q +angle R =180

angle P + x + 55 = 180

angle P +x=180-55

angle P +x = 125

angle P = 125 -x
