Question

Compute all angels of each of the figures below

Answer 1

2) In Triangle ABC,

/_CAB=70,/_QBR=145

/_PAB=180-70=110 (linear pair)

/_ABC=180-145=35 (linear pair)

Sum of angles in a triangle ABC=180

/_CAB+/_ABC+/_BCA=180

70+35+/_BCA=180

105+/_BCA=180

/_BCA=180-105=75

/_PCR=70+35=105

(The sum of interior angles opp/_PCR)
