Answer:
Step-by-step explanation:
The angles are complimentary, so they add to 90
6x + 3 + 7x + 9 = 90 Combine like terms
13x + 12 = 90 Subtract 12 from both sides
13x = 90 - 12 Combine
13x = 78 Divide both sides by 13
x = 6
<A = 6x + 3
<A = 6*6 + 3
<A = 36 + 3
<A = 39
A ray. it has line stopping point and goes on forever in the other direction.
