Question

Help me please I’ll give out brainliest ((Trigonometry))

Answer 1

Answer:

70.01 ft

Step-by-step explanation:

The angle of depression is 40°, which makes the angle formed by the ground and the line to the tower also 40°.

Since the side opposite of the 40° on the bottom is given, then you can use sine to find how far Ranger Bob is, since the line from him to the tower is the hypotenuse.

Let x = the hypotenuse

sin 40 = 45/x

x = 45/sin 40

x ≈ 70.01 (to the nearest hundredth)
