Question

Plzz tell this i will mark u as brainlist is it right

Answer 1

Answer:

Step-by-step explanation:

they have said that there r 2 tangents

the 2 tangents make an angle of 50°

∠OAB is twice of angle APB

∠APB=2 ∠OAB

50°=2 OAB

50°÷ 2 =OAB

OAB=25

Answer 2

Answer:

∠OAB = 25°

Step-by-step explanation:

From figure:

∠OBP = ∠OAP = 90°.

In Quadrilateral AOBP,

⇒ ∠AOB + ∠OBP + ∠APB + ∠OAP = 360°

⇒ ∠AOB + 90° + 50° + 90° = 360°

⇒ ∠AOB = 130°

In Isosceles triangle AOB,

⇒ ∠AOB + ∠OAB + ∠OBA = 180°

⇒ 130° + 2∠OAB = 180°

⇒ 2∠OAB = 50°

⇒ ∠OAB = 25°

Therefore, ∠OAB = 25°.
