Suppose a ramp 2 ft high makes an angle of 4.8° with the ground. Find the length of the ramp.
1 answer:
Answer:
23.9 ft (nearest tenth)
Step-by-step explanation:
Use the sine trig ratio to find the length of the ramp.
where:
is the angle
- O is the side opposite the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
- O = height of ramp = 2 ft
- H = length of ramp
Substituting the given values into the formula and solving for H:

I would compute sqrt(1 + 160pi^2) first to get approximately 39.75093337
Add this to 1 and we have 40.75093337
Then divide over 2pi to get a final approximate result of 6.48571248
So x = 6.48571248 is one approximate solution
In short, I computed only focusing on the plus for now.

If you were to compute you should get roughly -6.167402596 as your other solution. Each solution can then be plugged into the original equation to check if you get 0 or not. You likely won't land exactly on 0 but you'll get close enough.
