Answer:
15. False, m<1 and m<3 are not vertical
16. False, m<2 and m<4 are vertical, so they must be the same
17. True, they are supplementary
18. True, they are also supplementary
19. 90 - 35 = 55
20. m<7 = m<4, so it's 42 degrees
21. 126-90 = 36 degrees
22. 115-90 = 25, which gives us the angle of m<4, which is vertical to m<7, which means m<7 is also 25.
