Answer: ∠REA = 53°
Step-by-step explanation:
Since ∠BEA = 71°, set both angle measures equal to that.
2x + 5x + 8 = 71
Solve for x. First, combine like terms:
7x + 8 = 71
Then, subtract 8 from both sides:
7x = 63
Divide both sides by 7:
x = 9
Now, plug x into ∠REA:
∠REA = 5x + 8
∠REA = 5(9) + 8
∠REA = 45 + 8
∠REA = 53°
Hope this helps!
