Question

If one of the angles of a triangle is 40° and another one is 60°, what is the third angle??

Answer 1

Answer:

80°

Step-by-step explanation:

Explanation:

the property of a triangle is, all angles add up to 180°.

so, 60° + 40° + x ( the unknown angle which we have to find) = 180°.

100 + x = 180.

x= 80
