Explanation:
I'm happy to get you started, but I won't give you all of the answers.
Keep the following in mind (ONLY for parallel lines cut by transversal)...
These angle pairs are Congruent (equal):
Alternate Interior - on opposite sides of transversal but between the parallel lines (figure in Start box)
Alternate Exterior - opposite sides of transversal and outside of the parallel lines (see figure in bottom row, far left)
Corresponding - looks like the same location but "slid" up or down the transversal (see top row, 2nd box)
Vertical angles - on opposite sides of X created by just 2 intersecting lines (row 3, box 1)
These angle pairs are Supplementary (add up to 180°):
Same Side Interior - on same side of transversal and between the parallel lines (like box 3 in row 3)
Same Side Exterior - same side of transversal but outside of the parallel lines (row 2, box 1)
Linear Pairs - on same side of same line, sharing a side (none in this pic)
The answer in the Start box is x=141, so go to the left.
That box is x=39, so go down.
I hope this helps!!
