Question 1115980: A kite is flying on the end of a 17 m string which makes an angle of 41� to the horizontal. What is the kite's height above the ground? Assume that the string is taut and held 1 m above the ground, and that the ground is horizontal. Give your answer as a number of metres (not in scientific notation) and to two significant figures.
I've calculated it as 11 m but i think i'm missing out on something

The string length from person's hand to the kite is the hypotenuse of a right triangle. How high the kite is one of the legs, the leg wanted. Angle opposite this leg is given.

If y is the height of the kite then .

----------do what you need.

the string is taut and held 1 m above the ground,

That part means, you are looking for y+1.

If you calculator shows you 12.1530034928386 with maybe further digits after that, but you want TWO SIGNIFICANT FIGURES, then you want meters.

If the instructions said, "to the nearest hundredth" then you would report meters.
