Answer:

Angle of elevation of the airplane = 17.46 degrees

Step-by-step explanation:

From the picture attached,

An airplane is flying at an altitude of 1500 ft at point A.

Runway starts from point B from which distance of the airplane is 5000 ft.

Now we apply sine rule in the given triangle ABC to measure the angle θ.

sinθ = \frac{\text{Opposite side}}{\text{Hypotenuse}}

sinθ = \frac{AC}{AB}

       = \frac{1500}{5000}

\theta=\text{sin}^{-1}(\frac{3}{10})

\theta=17.46 degrees

Two cars leave towns 300 kilometers apart at the same time and travel toward each other. One car's rate is 16 kilometers per hou
julia-pushkina [17]
The cars travel with constant speed, and the equations of movement of each one are,

x_1=v_1t

x_2=x_0-v_2t

Where v_1=16 Km/h, v_2 is unknown, x_0 is 300 kilomters. As they meet in 2 hours, then t=2 and x_1=x_2, so,

x=v_1t

x=x_0-v_2t

Solving for v_2,

v_2=x_0/t-v_1=134\ \ Km/h
