Answer 2

Given angles of a triangle are 3x,2x + 20, 5x - 40.

We know that Sum of the angles in a triangle is 180

= > 3x + 2x + 20 + 5x - 40 = 180

= > 10x + 20 - 40 = 180

= > 10x - 20 = 180

= > 10x = 200

= > x = 20.

Then,

(1) 3x = 3(20)

         = 60


(2) 2x + 20 = 2(20) + 20

                    = 60


(3) 5x - 40 = 5(20) - 40

                  = 100 - 40

                  = 60.



Therefore the three angles are 60,60,60.



Hope this helps!
