Answer:

see explanation

Step-by-step explanation:

3)   line l and m are perpendicular so they intersect at 90 degrees

I labelled the angles that are the same measure.

2x + 23 = 90    subtract 23

2x = 67             divide by 2

x = 23.5 degrees

4) 2m + 66 = 120  subtract 66

2m = 54                 divide by 2

m = 27 degrees
