Question

In the adjoining figure l parallel m and P parallel q find the value of a, b, c and d​

Answer 1

∠b is transversal angle of 60°

So ∠b=60°

∠a+∠b=180°

∠a + 60° = 180°

∠a=120°

∠b and ∠c are vertically opposite.

So, ∠c=60°

∠c is complementary angle of ∠d.

So, ∠c+∠d=180°

∠d = 180-60 = 120°
