Question

SOMEONE HELP BECAUSE I DONT GET THIS

Answer 1

7x+40 = 3x+112

x=18

7(18)+40

<A = 166

Answer 2

x = 18

m<A = 166°

Explanation:

The parallel lines are cut by a transversal, so corresponding angles A and B are congruent.

7x + 40 = 3x + 112

4x = 72

x = 18

m<A = 7x + 40 = 7(18) + 40 = 126 + 40 = 166
