Question

The length of a string between a kite and a point in the ground is 90m . If the string is making is making an angle theta with the level ground such that tan theta = 15/8, how high will the kite be?

Answer 1

we get that:

$\theta=\arctan (\frac{15}{8})\approx61.92^{\circ}\rightarrow y=90\cdot\sin \theta\approx79.41m$
