Answer:
6) f=45
7) r=57
Step-by-step explanation:
the angles of a triangle will always add up to 180 degrees. Therefore, for the first one the three inside angles have to be 30, 15, and 135. If 135 is the supplementary angle to f, 45 must be the degree of f.
Same idea for the second one. 180-143=37. so 37+86+r=180. solve for r to get 57.
Answer:
I believe the last one is proportional
Step-by-step explanation:
simplify r/s and you will get your answer 5

The top line has 5 shaded squares
The next line has 5 shaded squares
The third line from the top has 2 squares
The fourth line from the top has 2 squares
The fifth line from the top has 2 squares
The sixth line from the top has 2 squares
Add them together
5+5+2+2+2+2 = 18
