Question

A = 6x – 18°
B = 14x + 38°

Answer 1

x = 8

<A = 30

Explanation:

6x - 18 + 14x + 38 = 180

Like terms

20x-20=180

subtract

20x = 160

Divide

x=8

Solve for <A

6(8) - 18

Simplify

48 - 18

30

Answer 2

the measure of A is 30 degrees

explanation:
(6x-18)+(14x+38)=180
x=8

6(8)-18=30
