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.

Yes, my calculator is in degree mode. Should it be in radians mode?Do you have your calculator in degree mode?

sin (70°)(65) = 50.3028943013 in radians mode.Try evaluating the expression again...

I say the answer is 50 meters.

Your expression is correct, but your numeric evaluation of that expression differs from mine.What number are you getting? Show me your set up.

your argument for sine is 70 degrees ... you need to be in degree mode.sin (70°)(65) = 50.3028943013 in radians mode.

I say the answer is 50 meters.
