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