Question

In an isosceles triangle each base angle is 30° greater than the vertical angle.
Find the measure of all the three angles of the triangles.​

Answer 1

Step-by-step explanation:

40,70,70

let the vertical angle be x

x+(×+30)+(×+30)=180

3×+60=180

3×=120

×=40

therefore,

vertical angle=×=40

each base angle=40+30=70
