Question

in the figure PQ parallel to RT find the value of a, b and c

Answer 1

Hii buddy!!!

Answer =

In triangle PQR
P + Q + R = 180° 【 sum of angles of triangle is 180°】
P + 55° + 80° = 180°
P + 135° = 180°
P = 180 - 135
P = 45°
P = c = 45°

P = a 【 correspoing angle】
a = 45°

80° + a + b = 180° 【linear pair】
80° + 45° + b = 180°
125° + b = 180°
b = 180 - 125
b = 55°
