Answer:
D..... 3 lines of Symmetry
We see two parallel lines crossed by a transversal.
The two labelled angles are alternate interior angles, hence they are equal.
The equality allows us to equate the two expressions and hence solve for x.
8x-3=5x+42
transpose terms
8x-5x=42+3
solve for x
3x=45
so x=45/3=15.
This means 5x+42=5*15+42=75+42=117 degrees.
Yes they are because some is negative and just put yes on your paper its kind of hard to explain i hope i helped you witu the question
This is what I got as my answer. Hope it helps!
