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 grou
1 answer:
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
because cos = opposite/hypotenuse. the opposite side is the ladder in this case. therefore your answer for how high up the slide is
because cos = opposite/hypotenuse. the opposite side is the ladder in this case. therefore your answer for how high up the slide is
