Answer:
See below
Step-by-step explanation:
d = 78° (Vertical angles)
h = 70° (Vertical angles)
Measure of angles d and h are are not equal. therefore they are not congruent.

Answer:
The constant of proportionality is 6
Step-by-step explanation:
Recall the equation for direct variation is
where
varies directly with
and
is the constant of proportionality. If we take any listed coordinate point, we can determine the value of
. I will use (20,120) as an example:

Therefore, the constant of proportionality is 6
36:12. 36 is the teeth on the front socket and 12 is the teeth on the rear socket.
All you need to do is simplify by finding the greatest common factor (GCF) of 36 and 12-which is 12, then divide by the GCF. This gives you 3:1. The gear ratio for the bike is 3 teeth on the front socket for every 1 teeth on the rear socket (3:1)
