From the given figure 7 ,find the value of x if AB is parallel CF and AE = DE, angle BAE = 38°.

*see the given given in the attachment below

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°

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
