You are making a welding fixture and must cut down a length of steel tubing from 19 3/8 inches to 11 9/16 inches. when you cut the tubing, you will waste 1/16 inch of it because of the width of the saw cut. if the leftover piece is long enough, you will use it in another fixture. how long will this leftover piece be?

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

wait nvm i know the correct answer now its 100%   81 square feet
