Question

What is the numerical sum of the degree measures of ∠DEA and ∠AEB?

Answer 1

<DEA and <AEB?

180

What are the numerical measures of the angles?

X= 14.5

m<DEA= 39.5

m<AEB=140.5

Explanation:

Answer 2

The angles are supplementary, therefore totaling them at 180°.

And because I'm bored, I'll solve for x for you!

(x + 25) + (9x + 10) = 180
10x + 35 = 180
Subtract 35 from both sides.
10x = 145
Divide by 10 on both sides.
x = 14.5
