Rosie is building a wheelchair ramp that is 30 feet long and 2.5 feet high. She needs to install a vertical support piece 20 feet from the end of the ramp. What is the length of the support piece in inches?

IF I'M NOT RIGHT CORRECT ME!!!

The length of the support piece is 25 inches

Step-by-step explanation:

First, set up the proportion for similar triangles:

30*h=(2.5)*(20)

30h=50

Step 2: Divide both sides by 30.

30h/30=50/30

h=5/3

5/3ft * 15 inches = 25 inches

Turn feet into inches that is: Length of the support piece is 25 inches

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
