Answer:
- The measure of ∠A is 66°.
Step-by-step explanation:
<u>We know that:</u>
- ∠A = 3x + 18
- ∠D = 4x + 2
- ∠D = ∠A
<u>Now, let's solve the equation. ∠D = ∠A.</u>
- => 3x + 18 = 4x + 2
- => -2 + 18 = x
- => 16 = x
<u>Now, let's substitute the value of x into any equation.</u>
- => 4x + 2
- => 4(16) + 2
- => <u>66°</u>
Hence, the measure of ∠A is 66°.
Answer:
9y + 24
Step-by-step explanation:
2(3y + 6) - 3(-4 - y)
= 6y + 12 - 3(-4 - y)
= 6y + 12 + 12 + 3y
= 9y + 12 + 12
= 9y + 24
