Solution

⇒ ∠ROP + ∠POT + ∠TOS = 180°

Linear pair

⇒ 4b + 75° + b = 180°

⇒ 5b = 180° – 75°

⇒ 5b = 105°

⇒ b = ¹⁰⁵/₅

b = 21°

Let's substitute this value in 4b and b :

ROP : 4b = 84°

TOS : b = 21°

⇒ ∠POT + ∠TOS = ∠ROQ

Vertically opp angles

⇒ 75° + b = 2c

⇒ 75° + 21° = 2c

⇒ 96° = 2c

⇒ ⁹⁶/₂ = c

c = 48°

On substituting :

ROQ : c = 48°

⇒ ∠POR = ∠QOS

Vertically opp angles

⇒ 4b = a

⇒ 4 × 21° = a

a = 84°

Now, we get :

POR : a = 84°

_____________________

The value of a, b, c are 21°, 84° and 48° respectively.
