Question

a slide 4.1 m long makes an angle of 35° with the ground. rounded to the nearest tenth of a meter, how far above the ground is the top of the slide.

Answer 1

By definition,

sin(angle) = opposite/hypotenuse

From the picture,

$\begin{gathered} \sin (35)=\frac{x}{4.1} \\ \sin (35)\cdot4.1=x \\ 2.4\text{ m = x} \end{gathered}$
