Answer:
the ramp's vertical distance is 60
Step-by-step explanation:
Think about what a ramp looks like from the side (right triangle). Use the Pythagorean Theorem.
[tex]H2 = a2 + b2[/tex]
The wheelchair ramp (hypotenuse) is given to be 109, if one of the sides is 91, simply plug in the numbers and solve for the other side.
[tex](109)^{2} = (91)^{2} + b^2[/tex]
[tex]11881 = 8281 + b^2[/tex]
[tex]3600 = b^2[/tex]
[tex]\sqrt{3600} = b[/tex]
[tex]60 = b[/tex]
Hope this helps!
