Question

in figure O is center of circle ifBACis130deegre find angle x​

Answer 1

Answer:

Step-by-step explanation:

X=180°,

It is parallel to diameter any straight line that is equal to 180°.

Answer 2

Answer:

∠ABC = ∠ACB = 25°

Step-by-step explanation:

W.K.T total sum of angle in a triangle = 180° (∵Angle sum property)

BA = AC (∵Radii of same circle)

∴ ∠ABC = ∠ACB (∵ Angles opposite to equal side)

Let ∠ABC = ∠ACB = X

∴ ∠A + ∠B + ∠C = 180°

130° + x + x = 180°

2x = 180° - 130°

x = 50° / 2

x = 25°

∴ ∠ABC = ∠ACB = 25°
