1. The pilot of an airplane at an altitude of 500 meters, the research at the edge of a runway into a depression angle of 31 degrees. To what extent the driver from the edge of the runway? The airfield is _________ meters driver.
A. 456.98
B. 583.36
C. 897.41
D. 970.87
2. A soldier looks at an elevation angle of 60 degrees to the mast of 50 feet. The extent of the soldier of the wave?
A. 28.87
B. 32.89
C. 37.98
D. 43.6
3. Robert stands on a cliff and looking into a depression angle of 62 degrees for a boat. The cliff is 76 meters high. How far is the ship from the cliff? Round answer to 2 decimal places. The boat is _________ meters from the cliff. HinT: Draw a picture.
4. A standing committee on tourism are the top 300 feet of the monument looks at an angle of 48 degrees of depression and sees a car parked on the street. What is the shortest distance between the tourist and the car? The distance is ____________ feet. Round your answer to two decimal places.

1)
SOH CAH TOA
The line that directly connects to the plane of the track is the hypotenuse. We are therefore in the NAS
Sin Θ = W / H
Θ = depression angle = 31 °
W = aircraft height = 500
H = distance between the plane of the band ....
A = W / sin Θ
A = (500) / sin (31) = 970802
2)
This is similar to the first question, unless the distance is the diagonal of the soldiers, but the horizontal distance from the mast. So we resolve on the side to side, and must use tanning beds Θ.
Θ = elevation angle = 60 °
Y = height of pole = 50
A = The horizontalDistance from the pole
A = W / tan Θ
A = 50 / tan 60
A = 28.8675
3)
This is the configuration that the first problem
Θ = 62 °
H = distance from the ship on the rocks
Y = height of cliff = 76
Sin Θ = W / H
H = W / sin Θ
H = 76 / sin 62 = 147.56
4.
This is another aspect of depression
Θ = 48
O = 300
H = shortest distance between tourism and the automotive industry
Sin Θ = W / H
H = O / sinΘ
H = 300 / free (48) = 403.69
2 is because in a 30-60-90 triangle is opposite the angle 60degree x [square root of 3]. To find the part you need, what is x divided by the square root of 3 and I ~ 28.8675135.
Otherwise, I do not know. I was not good with an angle of depression. Actually, I should say more about it. Lol.
Certainly # 2 is A.
