Answer:

x = 93

Step-by-step explanation:

*for angle labels, see picture below

Using angle addition postulate, we can say that angle EAC is the sum of angle CAB and angle BAE:

m<EAC = m<CAB + m<BAE

m<EAC = x + 39

Since line l and m are parallel, you can say that angle ACD is an alternate interior angle to angle EAC. This means they are equal.

Now, we can write an equation to solve for x:

m<EAC = m<ACD

x + 39 = 132

x = 93

Answer:

x=93°

Step-by-step explanation:

If l ıı m

l=180° ; 132°+?(y) =180° (Co-interior angle)

Find the value of y

132°+y=180°(Transpose)

y=180°-132°

y=48°

...

Find x

39°+x+48°=180°(Transpose)

x=180°-48°-39°

x=93°
