The y row changes by 3 each spot. The x row changed by 4 each spot. So the slope is 3/4x.
To prove the SAS (side-angle-side) postulate, a. <XWY=<ZWY needs to be marked congruent. Since the segment WY=WY due to the reflexive property, we need an angle between them to prove SAS, which has to be XWY and ZWY.
10 more than (+) twice a number (2x) is (=) 36
10 + 2x = 36 Subtract 10 from both sides
2x = 26 Divide both sides by 2
x = 13
Parallel bc the slopes the same!
