Question

11. if _POR and LQOR form pair and a-b=80, then find the value of a and b.​

Answer 1

Answer:

a=130° b=50°

Step-by-step explanation:

∵ ∠POR and ∠QOR form the

linear pair.

=> ∠POR + ∠QOR = 180°

=> a + b = 180° …(1)

a – b = 80° …(2)

Adding Eqn. (1) & (2)

2a = 260 => a = 130°

From Eqn. (1)

130° + b = 180° => b = 50°

a = 130°, b = 50°
