C.
The graph looks like it’s linear and is trending in an increasing way.
1 km = 1000m
1 hr = 3600 s
189 km/h
189 * 1000 / 3600 m/s
189*5/18 m/s
945/18 m/s
315/6 m/s
105/2 m/s
52.5 m/s
in 10 s
52.5*10
525 m
Each means to multiply I dont know if thats the word you are asking to us to define
Angles B and D are congruent so:
(360-112-74)/2=87°
