Answer:
m∠A=42
Step-by-step explanation:
Since they are complementary they must add up to 90°.
(2x+30)+(6x+12)=90
We can just remove parenthesis since you can't really do anything with them.
2x+30+6x+12=90
Combine like terms.
8x<u>+42</u>=90
Do inverse to find the value of x.
<u>8x</u>=48
x=6
Now since we are looking for the m∠A and not x we need to replace the x with the value of x in the ∠A equation.
(<u>2(6)</u>+30)
(<u>12+30</u>)
m∠A=42
