ALSO UPPING POINTS TO 25

Approximately 460 ft

Step-by-step explanation:

In any question where we have:

And we're asked to find:

We're gonna be using some trigonometry. The first question we've gotta ask is what we're looking for, and how the angles and sides relate to that. We're given:

And we're looking for:

How do our sides relate to the angle? Well, the 400 ft side is adjacent to 49°, and the side h is opposite. From SOH-CAH-TOA, we can see that the last trig function, tangent, is equal to opposite/adjacent. Let's turn this into an equation to bring it all together:

Solving for h, we find that

So the heigh of the hill is approximately 460 ft.

the answer is d. (1.2, -4.7) on edgn
