Step-by-step explanation:
the given data is
tanθ = 2.773 and 0<θ<π/2
this implies θ = tan inverse(2.773)
⇒ θ = 70.16°
Therefore, sinθ = sin70.16° = 0.9406
similarly,cosθ = cos70.16° = 0.3393
therefore, values of sinθ and cosθ are 0.9406 and 0.3393 respectively.
Answer:
i don't no the answer but this formula may help whoever answers
To answer the question, convert first the distance of 3000 miles to kilometers by the conversion factor 1 mile is 1.61 kilometer.
(3000 mi) x (1.61 km / 1 mile) = 4830 km
The time it would take to travel this distance is the quotient of distance divided by speed.
time = 4830 km / (10 km / h) = 483 h
Thus, the answer is 483 hours.
