Question

one of the angels of a triangle measures 80° and the other two angles are equal. find the measure of each of the equal angles.

Answer 1

Sum of the angles of triangle are 180
One is 80 then 180-80=100 divided by 2= 50

Answer 2

as we know that sum of all the angles of a triangle is 180 degree
so,the the angles be x
then, 80+x+x=180 degree
80+2x=180
2x=180-180
2x=100
x=100/5
=50
so the equal angles are 50 degrees
