Answer:the answer is D
The correct answer is D. This is because it is a 30-60-90 triangle, meaning the hypotenuse is 2x more than the smallest side, and the longest side is the short side times the square root of three.
Slope = - 4
(-2,8) and (0,0)
In order to solve this problem, we can start by drawing a diagram of the given situation. (see attached picture)
As you may see, we have a right triangle there, so we can use trigonometric functions to solve this. Specifically, the sine function.
in this case we need to find the hypotenuse, so we solve the equation above for the Hyp, so we get:
in this case, the opposite side (OS) is the heght of the helicopter, the angle is the 42° and the Hyp is the direct distance between the helicopter and Jackson, so we substitute the given data to get:
