Answer:
x = 109°
Step-by-step Explanation:
Since AB is parallel to CF, m<BAE = m<AED = 38° (alternate interior angles are congruent)
Since AE = DE, ∆AED is an isosceles ∆.
The two base angles of any given isosceles ∆ are said to be congruent.
This means, m<EAD = m<EDA = ½(180 - m<AED)
m<EDA =
m<EDA =
x + m<EDA = 180° (angle on a straight line)
Value of x = 109°
