Answer:

Step-by-step explanation:



X+x+54=180
2x+54=180
2x=126
x=63
63+54=117
one angle is 63, the other is 117
Step-by-step explanation:
Circumference of wheel = πd = 0.75πm.
How far the car travels per minute
= 60s * (14m/s) = 840m.
Hence number of revolutions per minute
= 840m / 0.75πm
= 356.507....
= 357. (nearest whole number)
