Question

In an isosceles triangle if vertical angle is 50° then the measure of each base angle is ​

Answer 1

65 is the correct answer.

EXPLANATION:

Sum of all three angles = 180.

Sum of the other two angles other than vertical angle = 180 - 50 = 130 degrees.

Therefore, one of the angles is=

130 ÷ 2 = 65, which is the measure of each base angle.

Answer 2

Answer:

HII FRIENDS

HOPE MY ANSWER HELPS YOU

Step-by-step explanation:

Let us consider the problem:

let the isosceles triangle, base angles are of equal measurement,

Therefore, 50

each base angle sum of both base angle =50

+50

=100

sum of three angle is 180

Find vertical angle

sum of three angle = sum of base angle + vertical angle

180

=100

+ vertical angle

vertical angle =180

−100

=80
