The ramp is modelled as shown in the diagram below.
The angle of elevation from the car is the angle form by the horizontal line and the observer eye from the car. In the diagram, this angle is marked by

We use trigonometry ratio to work out the value of

When doing vertical subtraction, 800 - 675 will turn out like this:
800
- <u>675

</u>You should know that we start on the right and then end on the left.
<u>
</u>So, we do 0 - 5, 0 - 7, then 8 - 6, right?
No. We have to borrow because you can't have a negative number when doing each number individually, only until the end. In this case, there won't be any negative numbers.
<u>
</u>You can't do 0 - 5 or 0 - 7, so you have to borrow, changing the number to the left of it one lower (unless it's 0, so then you must borrow the the next number after that).<u>
