Answer:
Step-by-step explanation:
By triangle <u>similarity</u><u> </u><u>theorem</u> we acquire:
since AE=AD+ED substitute:
simplify addition:
cross multiplication:
distribute:
simplify multiplication:
cancel 130 from both sides:
divide both sides by 10:
so, the measure of side AE=20.8+13=<u>3</u><u>3</u><u>.</u><u>8</u>

Answer:
- 8π radians/second
- 527.8 meters
Step-by-step explanation:
A) The angular velocity is the ratio of angular distance to time:
ω = 1 revolution / (0.25 s) = (2π radians)/(0.25 s)
ω = 8π radians/second
__
B) The arc length is ...
s = rθ = rωt
s = (35 cm)(8π rad/s)(60 s) = 16,800π cm
s ≈ 52779 cm = 527.79 m
The wheel travels about 527.8 meters in one minute.
