Question

In an isosceles triangle ABC the measure of vertex angle A is 30 degree more than the measure of each base angle.Find the measure of each angle of the triangle

Answer 1

Let the Base angles be x

Now vertex angle is x+30°

Now,
x+x+3x=180°
5x=180°
x=36°

The Base angles are 36°
The vertex angle is 36°+ 30°=66°

Answer 2

let equal angle X
⤵⤵⤵⤵⤵
X+X+30=180
2x=150
x=75

your answer is 75✔✔✔✔
