Vertical angles are congruent. Find the measure of angle x.
X
o
38°
x = [?]
Ente

We can solve this problem by:-

Here,

X=38°(Being vertically opposite angle)

So, X=38°

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
