1. name a pair vertical angels
< 2 and < 5
< 2 and < 6
< 3 and < 4
< 5 and < 6
2. if m < 1=53 what is m < 4
53
43
37
27
3. if m < 1=50 what is m < 5

Simple,

1.) A vertical angle, is an angle directly across another angle. Thus, <2 and <5 are vertical angles.

2.)This is another pair of vertical angles, thus, m<4 is 53.

3.)Since m<1 is 50

You have the m<4 which is 50. You already have m<3 which is the right angle, 90. 

Thus, 90+50=140

You know a line is supposed to be 180 degrees. So take,

180-140=40

Thus, the m<5 is 40.
