## anonymous 4 years ago When an airplane leaves the runway, its angle of climb is 18 degrees and its speed is 275 feet per second. Find the plane's altitude after 1 minute.

|dw:1328140802166:dw| trigonometry. use tangent function formula. . tan A= opposite side/ hypotenuse. . given the hypotenuse and the angle, you can find the altitude of the plane. .

$\sin 18=\frac{x}{16500}$

tan = opposite/hypotenuse??????? jerwyn? I thought tangent was opposite/adjacent.

5. Mertsj

$x=16500(\sin18)=5098.78$

How long will it take the plane to climb to an altitude of 10,000 feet? 16,000 feet?

ooh i'm sorry i was thinking of sine. . lol.. thanks mertsj for the correction!
