Question

one of the angles of a triangle is 106 degree and the other two angles are equal find each of the equal angles

Answer 1

As we know that
The sum of all the angle of triangle = 180°
so
Let us consider the unknown angle be x
x+x+106°=180°
2x=180°-106°
2x=74°
x=74/2
x=37°
Both the unknown angle will be of 37° each

Answer 2

let the angles is x
both angles are equal
sum of angle of triangle = 180°
106+x+x = 180
106+2x = 180
2x = 180-106
2x = 74
x = 37
so the measure of angles is 37 degree
