Question

if two angles in a triangle are 50 and 20 then what is the third angle ?

Answer 1

Hey !!

Given,

Two angles are 50 and 20.

Let third angle be x

Sum of all angles in a triangle is 180

ATP,

x + 50 + 20 = 180

x + 70 = 180

x = 180 - 70

x = 110

Therefore, the third angle is 110.

Answer 2

according to angle sum property of a triangle ,

angle 1 + angle 2 + angle 3 = 180°

50° + 20° + angle 3 = 180°

70° + angle 3 = 180°

angle 3 = 180°-70°

angle 3 = 110°

hope my answer helps you :)
