Question

in this given figure find angle BOC

plz give me ans. fast​

Answer 1

Answer:

X + (X+10) + (X+20) = 180

3X + 30 = 180

3X =150

X = 50

Answer 2

Answer:

70°

Step-by-step explanation:

We can solve this question by identifying that ∠AOB is a straight angle.

A straight angle is one that measures 180°. So,

(x + 10)° + (x)° + (x+20)° = 180°

⇒ (3x + 30)° = 180°

⇒ 3x° = 150°

⇒ x° = 150/3 = 50°

To find ∠BOC,

∠BOC = (x + 20)°

⇒ ∠BOC = 50° + 20°

⇒ ∠BOC = 70°

Hence, ∠BOC measures 70°. Hope it helps!
