At maximum speed, an airplane travels 2,400 miles against the wind in 6 hours. Flying with the wind, the plane can travel the sa
Hatshy [7]
X - y  = 2400/6 = 400        where x = speed of plane and y = speed of wind.

x + y =  2400/5 = 480          - flying with the wind

adding the 2 equations 
2x = 880
x = 440

Speed of the plane with no wind = 440 mph

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)
Eduardwww [97]

Given:

The figure of a right triangle. PO=12,m\angle O=y^\circ and perpendicular = 12.

To find:

The measure of angle y.

Solution:

In a right angle triangle,

\sin\theta=\dfrac{Perpendicular}{Hypotenuse}

In the given right angle triangle,

\sin y^\circ=\dfrac{7}{12}

y^\circ=\sin ^{-1}\dfrac{7}{12}

y^\circ=35.685335^\circ

y^\circ\approx 35.69^\circ

Therefore, the measure of angle y is y^\circ =35.69^\circ.

Therefore set your equation equal to 90 to find angle of x

53+x=90

Subtract 53 from both sides

X= 37 degrees
