Question

the two interior opposite angle of an Interior angle of a triangle are 60 degree and 80 degree find the measure of the interior angle

Answer 1

Angle A+ Angle B + Angle c = 180°

60+80+ angle c = 180°

Angle c = 180°-140°

Angle c = 40°

Answer 2

Interior angles of a triangle are=180
So there are two angles are =60+80=140
So remains =40
Angeles are =60,80,40
