Question

in the given figure ab = AC and Angle ACD is equal to 125 degree find angle A

Answer 1

Answer:

Hello dear.. where is the figure?

Answer 2

Answer:

Given AB = AC

therefore , angle B = angle C

Now from linear pair

angel C + angle ACD = 180⁰

angel C + 125⁰ = 180⁰

angel C = 180⁰ - 125⁰

angel C = 55⁰

therefore , angle B = angle C = 55⁰

Now ,

angel A + angle B + angle C = 180⁰

angel A + 55⁰ + 55⁰ = 180⁰

angel A = 180⁰ - 150⁰

angel A = 30⁰
