Question

A boy flying his kite releases the entire length of his string which measures 41 m, so that the kite is 31 metres above him.If the angle the string makes with the horizontal ground is 0°, find 0 to two decimal places.

Answer 1

By definition,

sin(angle) = opposite/hypotenuse

From the picture,

`\begin{gathered} \sin (\theta)=(31)/(41) \\ \theta=\arcsin ((31)/(41)) \\ \theta=49.12\text{ \degree} \end{gathered}`
