Question

in an isosceles triangle the base angles are equal the vertex angle is 40° the measure of the base angles of thetruangle will be
​

Answer 1

Step-by-step explanation:

sum of all angles in a triangle is 180 degrees .

so, let base angle be ×.

as base angles are equal , they are 2×.

2× +40=180

2×=180-40

2×=140

×=140÷2

×=70

Therefore the measure of the base angles of the triangle is 70 degrees

Answer 2

Step-by-step explanation:

2×+40=180

2×=180_ 40

2×=140

×=140÷2

×=70
