Akite is 15m up in the sky. The angle the string makes with the ground is 50 degrees. How long is the kite string?

A picture would help with this one...

It's going to be a right triangle. The height is going to be 15m. The lower angle is 50 degrees. We're trying to find the hypotenuse, so assign that a variable like x. You can use the sine function, which I'm sure you learned in class for this. Sine is opposite over hypotenuse.

sin 50 = 15/x

Solve that equation for your answer.

You have to use SINE.

If you draw a diagram you know that we are looking for the hypotenuse.

Therefore sin50=15/x

0.766=15/x

0.766x=15 (divide by 0.766 to isolate x)

x=19.58

so the kite string is 19.58m long
