Question

in the given figure angle APB equal to 50 degree find angle Oab​

Answer 1

Answer:

Step-by-step explanation:

Since OA is perpendicular to PA and also, OB is perpendicular to PB

∠APB + ∠AOB = 180°

50°+ ∠AOB = 180°

∠AOB = 180° –  50° = 130°

In △AOB,

OA = OB = radii of same circle

∠OAB = ∠OBA = x ( say )

Again, ∠OAB + ∠OBA + ∠AOB = 180°

x +x + 130° = 180°

2x = 180° –  130° = 50°

X = 25°

Hence, ∠OAB =25°

Answer 2

Answer:

bisect angle AOB

it forms an eq triangle

find angle POA and twice it

65+65=130
