Answer:

x =14

<A = 7x -11 = 87

<B = 2x-3 = 25

<C = 5x -2 = 68

Explanation:

The sum of the angles add to 180

7x -11 + 2x-3 + 5x-2 = 180

Combine like terms

7x +2x+5x -11-3-2 =180

14x-16=180

Add 16 to each side

14x-16+16 =180+16

14x = 196

Divide each side by 14

14x/14 =196/14

x =14

<A = 7x -11 = 7*14 -11 = 98-11 = 87

<B = 2x-3 = 2*14 -3 = 28-3 = 25

<C = 5x -2 = 5*14 -2 = 70-2 = 68
