Question

If A, B and C all lies on a straight line, if A = 72° and B = 38°, find C.​

Answer 1

Answer:

HEY MATE!!! HOPE YOU FIND THIS.

Step-by-step explanation:

∠A + ∠B + ∠C = 180° (Sum of all angles on a straight line is 180°)

72° + 38° + ∠C = 180°

110° + ∠C = 180°

∠C = 180° - 110°

∠C = 70°

Hence, measure of ∠C is 70°
