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 base angle x
so angle A is 30+x

use angle sum property
30+x+x+x=180
3x=150
x=50

so angle A is 80 and base angle is 50

Answer 2

Answer:

Step-by-step explanation:

Angle a=. 80

Angle b=. 50

Angle c=. 50
