Question

a slide 4.1 meters long make an angel of 35 degress with the ground . to the nearest tenth of the meter , how far above the ground is the top of the slide?

Answer 1

So to do this we need a little trig. picture a slide with a ladder, the slide would be the hypotenuse and the ladder would be the vertical side. and since we know the slide makes a 35 degree angle with ground we can solve by using the cosine function
$\cos(35) = \frac{x}{4.1}$
because cos = opposite/hypotenuse. the opposite side is the ladder in this case. therefore your answer for how high up the slide is
$x = 4.1\cos(35)$
$x = 3.335 \: meters$
