Question

The base angles of an isosceles triangle are equal and vertex angle measures 80°​

Answer 1

Since both the base angles are equal and also we know that sum of all three angles of a triangle is equal to 180 degree, so the equation we get is:

2X + 80 = 180

2X = 180 - 80 = 100

X = 100/2 = 50°

Ans: Base angles are equal to 50°
