Question

PQ is a tangent to a circle with center O .If OAB 30,find ABP and AOB

Answer 1

Answer:

using tangent theorm we will get OPB 90 degree the prove the rest

Answer 2

Answer:

Step-by-step explanation:

ANGLES:-.  

Angle OAB = 30° .

TPT:-.

Angle ABP = ? = x .

Angle AOB = ? = x .

PROOF :-.

OAB + ABP + AOB = 180° . ( Angle sum property ) .

30° + x + x = 180° .

2x = 180° - 30° .

2x = 150° .

x = 150° / 2 .

x = 75° .

Hence proved .
