A pilot flying at an altitude of 1.8km sights the runway directly in front of her. The angle of depression to the beginning of t

Dennis_Churaev [7]

Answer:

The answer is a

Step-by-step explanation:

The distance from the near end of the runway to the plane, divided by the altitude is the tangent of (90 degrees minus the angle of depression). Let "d1" be the distance to the near end of the runway, and "d2" be the distance to the far end of the runway. Let "a" be the altitude of the plane.

d1/a = tan(90 - 31)

d1 = a*tan(90 - 31)

d2/a = tan(90 - 23)

d2 = a*tan(90 - 23)

runway length = d2 - d1 = a*(tan(67) - tan(59))

length = 1800*(.6916) = 1245m = 1.2km

the answer is "a"

Length of the hypotenuse of the triangle to the nearest tenth of a metre

Lemur [1.5K]

Answer:

The length of the hypotenuse is 2.4m

Step-by-step explanation:

well to start we have to know the relationship between angles, legs and the hypotenuse

α = 55°

o: opposite = 2.0m

h: hypotenuse

sin α = o/h

cos α= a/h

tan α = o/a

we see that it has (angle, hypotenuse, opposite)

we look at which meets those data between the sine, cosine and tangent

is the sine

sin α = o/ah

Now we replace the values and solve

sin 55 = 2.0/h

0.81915 = 2.0/h

h = 2.0 / 0.81915

h = 2.4415 m

round to the nearest tenth

h = 2.4415 = 2.4 m

The length of the hypotenuse is 2.4m
