Aslide 3.1 m long makes an angle of 35° with the ground. to the nearest tenth of a meter, how far above the ground is the top of the slide?

Height of the slide from the ground = 1.80 m

Step-by-step explanation:

In this question the given values are length of the slide is 3.1 m and the angle of slide with the ground = 35°

Now if we imagine the triangle formed by slide and ground will be a right angle triangle so we can apply sin rule to get the height of the slide from the ground.

Now we know sin ∅ = height / hypotenuse

Here ∅ = 35° and hypotenuse = 3.1

Therefore sin∅ =

Or height x = 3.1 sin 35°

x = (3.1) × (.57) = 1.77 ≈ 1.80 m

The height of the slide from the ground is 1.80 m.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
