Answer:
a) Angle 1: 80°
Angle 1 = Angle 5
(corresponding angles)
Angle 5:
180 - 100 = 80°
Supplementary angles
b) Angle 8: 80°
Angle 8 = 180 - Angle 6 = 180-100 = 80
(Supplementary angles)
c) Angle 2: 100°
Angle 2 = Angle 6
(Corresponding angles)

The answer to the question above is 2.4
Answer:
By a quick online search, i found two tape diagrams:
13) You: -
Friend: - -
So you have one block, and your friend has two.
We know that you work for 3 hours, this means that your only block must represent 3 hours.
And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.
Then in total, he tutored for 3 hours + 3 hours = 6 hours.
14) You: -
Friend: - - - - -
In this case, you still have only one block, but now your friend has 5.
Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:
5*3 hours = 15 hours
