For a problem of this nature, we need to assume that the base of the observation tower is at the same elevation as the fire. The tangent of the angle is the ratio of tower height to horizontal distance:
tan(α) = (tower height)/(horizontal distance)
Rearranging this equation, we have
(horizontal distance) = (tower height)/tan(α)
Putting in the given values gives
(horizontal distance) = (90 ft)/tan(7°) ≈ 733 ft
Answer:
2/52
Step-by-step explanation:
If he took one ace out of 52 cards then it would have been 4/52
but as he's taking 2 aces out of 52 cards it is 2/52
This is the answer of this question
The diagonal of the dvd cover is 9 inches since there is a ratio of 12:1 and 9 feet divided by 12 is 9 inches
