Me on this equation! equation practice with angles..

x = 18, ∠A = 166°

Step-by-step explanation:

The relationship between ∠A and ∠B is that they are corresponding angles, which means they are congruent (equal).

   ∠A    =    ∠B

7x + 40 = 3x + 112

4x + 40 =         112           subtracted 3x from both sides

4x         =          72           subtracted 40 from both sides

 x         =  18                    divided both sides by 4

∠A = 7x + 40

    = 7(18) + 40

    = 126 + 40

    = 166
