Question

A slide 3.1 meters long makes an angle of 53 degrees with the ground. To the nearest tenth of a meter, how far above the ground is the top of the slide?

Answer 1

2.48 m

Explanation:

Length of slide = 3.1m

Angle, θ = 53°

We could find h using Pythagoras rule :

Sinθ = opposite / hypotenus

Sin53° = h / 3.1

0.7986355 = h / 3.1

0.7986355 * 3.1 = h

h = 2.4757700

Height of slide above the ground = 2.48 meters
