We know that sum of angles of a traingle is 180°

Given :Three angles (2x+2)° ,x° &(2x-7)°

\bold{\boxed{Sum\: of \:angles \:of \:a \:traingle =180°}}

Sumofanglesofatraingle=180°

= > 2x + 2 + x + 2x - 7 = 180=>2x+2+x+2x−7=180

= > 5x + 2 - 7 = 180=>5x+2−7=180

= > 5x - 5 = 180=>5x−5=180

= > 5x = 185=>5x=185

= > x = \frac{185}{5} = 37=>x=

5

185

=37

First angle is (2x+2)°=2×37+2=\bold{\red{76°}}76°

second angle is x=\bold{\blue{37°}}37°

Third angle is (2x-7)°=2×37-7=74-7=\bold{\green{67°}}67°

Now ,check :-

\bold{\boxed{{\red{76° }}+{\blue{ 37°}}+ {\green{67 °}}= 180°}}

76°+37°+67°=180°
