Question

40°, 80°,Find the measure of the third angle of triangle whose two angles are given.

Answer 1

Given,

Angles = 40 and 80

Sum of all angles in triangle =180

ATP,

x + 40 + 80 = 180

x + 120 = 180

x = 180 - 120

x = 60

Answer 2

40°,80°

The sum of the angles in a triangle is 180°. 
let the required angle be x

40°+80°+x=180°
120°+x=180°
x=180°-120°
x=60°...ans
