Question

in an isosceles triangle the base angles are equal if each base angle is twice of the vertex angle what are the degree measure of the angle of the triangle

Answer 1

Let the mesure of each vertex angle be x
so the mesure of base angle would be 2x
sum of all 3 sides of triangle are 180
so we have
2(2x)+x=180
5x=180
x= 36°

x=36°
2x=72°

Answer 2

Answer:

72°, 72°, 36°

Step-by-step explanation:

Let the mesure of each vertex angle be x

so the mesure of base angle would be 2x

sum of all 3 sides of triangle are 180

so we have

2(2x)+x=180

5x=180

x= 36°

x=36°

2x=72°
