Answer:

x = 18

< A = 166

Explanation:

Angles A and B are corresponding angles, therefore they have the same measure. Using this information, you get the following equation:

7x + 40 = 3x + 112

-3x - 3x

4x + 40 = 112

- 40 - 40

4x = 72

Divide both sides by 4.

x = 18

Solve for A:

7(18) + 40 = 166

Hope it helps!

Answer:

Angle A = 180

Explanation:

180=7x+40

Subtract 40 from both sides

140 = 7x

Divide 7 from both sides

20=x

Substitue 20 in for x

7(20)+40

140+40 = 180
