For a Science fair project, a group of students tested different Materials used to construct kites. The instructor gave to the group an instrument that accurately measures the angle of elevation. In one of the tests, the angle of elevation was 63.4° with 670 ft of string out. Assuming the string was taut, how high was the kite?

$$\sin \theta= \frac{opp}{hyp}$$
$$\sin 63.4°= \frac{x}{670}$$
$$670\sin 63.4°= x$$
$$x \cong 360.5 \implies 360.5$$
