Question

the vertical angle of the isosceles triangle is twice the sum of its base angle find each angle of the triangle ​

Answer 1

Answer:

vertical angle is 120

base angles are 30

Step-by-step explanation:

as given

vertical angle =2×sum of base angle

p=2×x+x

p=4x

p+x+x=180

4x+2x=180

6x=180

x=30

p=4x

p=120
