Question

Serious answers please:

Draw a picture of these if possible

1. a 24 foot ladder makes a 58 defree angle with the ground with many feet up a wall will it reach? Show four decimal places.

2. A ship's sonar finds that the angle of the depresion to a wreck on the bottom of the ocean is 13.2 degrees. If a point on the ocean floor is 75 meters directly below the ship how many meters to the four decimal places is it from that point on the ocean floor to the wreck.

To four decimal places find the angle of the elevation of the sun if a building 125 feet tall casts a shadow 196 feet long.

Answer 1

1.
If h is the distance up the wall, then:
h / 24 = sin(58deg)
h = 24sin(58deg)
= 20.3532ft.

2.
If x is the required distance, then:
75 / x = sin(13.2deg)
x = 75 / sin(13.2deg)
= 328.4419m.

3.
If x is the required angle, then:
tan(x) = 125 / 196
x = 32.5279deg.

Answer 2

I can't draw here but I will show you how I got the answers:

1) sin(58deg) = x/24
0.8480481 = x/24
x = 20.3532 ft

2) tan (13.2deg) = x/75
0.2345478 = x/75
x = 17.5911 m

3) tan x = 125/196
tan x = 0.6377551
x = 32.5279 deg
