Answer:

0.8 inches

Step-by-step explanation:

< R = 180-23-22 = 135°

the length of s = 1.5 × sin 23° / sin 135°

= 1.5 × 0.391 / 0.707 = 0.5865/0.707

= 0.8 inches

A wheelchair ramp with a length of 109 inches has a horizontal distance of 91 inches. What is the ramp's vertical distance?

Viktor [21]

Answer:

the ramp's vertical distance is <u>60</u>

Step-by-step explanation:

Think about what a ramp looks like from the side (right triangle). Use the Pythagorean Theorem.

$H2 = a2 + b2$

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.

$(109)^{2} = (91)^{2} + b^2$

$11881 = 8281 + b^2$

$3600 = b^2$

$\sqrt{3600} = b$

$60 = b$

Hope this helps!
