Question

If two angles in a triangle are 60° and 40° then the third angle will be :
(A) 110°
(B) 80°
(C) 40°
(D) 60°

Answer 1

Answer:

80°

Step-by-step explanation:

Sum of angles in a triangle is 180°

So if two angles are 60+40= 100°

Then the third angle will be 180-100= 80°

Answer 2

We know sum of angles in a triangle is 180
So
60+40+ third angle=180
Third angle is 80
