Question

Whfind the measure of Angle A Angle B and angle C in the given figure ​

Answer 1

Hey there!

Answer:

∠A = 30°

∠B = 120°

∠C = 60°

Step-by-step explanation:

The triangle inscribed in a circle is isosceles Δ because it's two sides are the radius of same circle and radii of same circle are equal.

∠A = 30°   (base ∠s of isosceles Δ are equal)

Now,

30 + 30 + ∠B = 180  (angle sum property)

60 + ∠B = 180

∠B = 180 - 60

∠B = 120°

Now,

∠C + ∠B = 180  (straight line property)

∠C + 120 = 180

∠C = 180 - 120

∠C = 60°

Hope It Helps You!
