Answer:
The height of the incline is 462 feet
Step-by-step explanation:
Here, we are asked to calculate height, given the angle of elevation.
When we talk about angle of elevation, we refer to the observation angle that we have when we look up from a position which is at the base.
Please check attachment for diagrammatic representation of the question terms.
From the attachment, we can see that we have a right angled triangle. We are asked to calculate the opposite given the adjacent.
Thus the trigonometric identity to use is the Tangent
Tan 30 = h/800
h = 800 * Tan 30 = 461.88 approximately 462 feet
Options in 3rd and 4th questions are wrong!. Hope it helps :)
Answer: Optional
Step-by-step explanation:
Since c is greater than d, 2c would be greater than 2d, because when it’s like this 2c
It sometimes means multiply.
