Question

the measure of the vertex angle of an isosceles triangle is 48°. what is the measure of each base angle?

Answer 1

66°

Explanation:

the base angles of an isosceles triangle are equal

the sum of the 3 angles in a triangle = 180°

subtract the vertex angle from 180 and divide the result by 2

base angles = 180° - 48° = 132°

base angle =
`(132)/(2)` = 66°
