# Kite Distance Above the Ground

Kaila is flying a kite whose string is making a 70° angle with the ground. The kite string is 65 meters long. How far is the kite above the ground?

I am thinking the sine function.

sin (70°) = h/65, where h is the distance of the kite above the ground.

sin (70°)(65) = h

27.08617 = h

I will say the kite is 27 meters above the ground.

Do you have your calculator in degree mode?

Yes, my calculator is in degree mode. Should it be in radians mode?

Try evaluating the expression again...

sin (70°)(65) = 50.3028943013 in radians mode.

I say the answer is 50 meters.

I'm getting a different number.

Your expression is correct, but your numeric evaluation of that expression differs from mine.

your argument for sine is 70 degrees ... you need to be in degree mode.

Understood.
