Question

The vertical angle of an isosceles triangle is 100°. Find the values of X and Y.

Answer 1

Heyyyy,

Angles other than the vertical angle in an isosceles triangle are equal.so let the other angles be x and x.
So,
x+x=80(angles in a triangle add up to 180°)

2x=80
x=40

Hence the other angles are 40°each
