Question

please answer থে following questions​

Answer 1

Step-by-step explanation:

Given :

AB||CD

angle APQ = 70°

angle PRD = 120°

Solution :

angle PRD + angle BPR = 180°

[Consecutive interior angle]

120° + angle BPR = 180°

angle BPR = 180° - 120°

angle BPR = 60°

angle APQ + angle QPR + angle BPR = 180°

[Straight line]

70° + angle QPR + 60° = 180°

130° + angle QPR = 180°

angle QPR = 180° - 130°

angle QPR = 50°

Answer 2

Answer:

b) 60° is the correct answer
