Here is a diagram:
..........................2km...............** ...........................*.....................* y .........*........9.............................* **************************************** .......................x The 9 degree angle is opposite the height (side y) and the 2km is the hypotenuse. The side "x" is not needed. You should know that sin=oppo/hyp That is sin(9)=y/2 solve for y.
