Answer:
m∠AEB=115°
Explanation:
we know that
Vertical Angles are the angles opposite each other when two lines cross. Vertical angles are always congruent.
In this problem
m∠AEB=m∠CED -----> by vertical angles
substitute the values

Solve for x



Find out the measure of m∠AEB
m∠AEB=(5x-10)°
substitute the value of x
m∠AEB=(5(25)-10)=115°
