1) 30% - 212.52/(427.25+212.52+75)
2) 893.59
Total amount spent on Flooring (427.25+212.52+75) = 714.87
Amount spent on furniture = 714.87 * 1.25= 893.59
3) 13%
(893.59-558.49-893.59/4)/893.59
As we move from point Z to point Y, x increases by 8 and y increases by 3. Thus the length of line segment ZY is sqrt(8^2 + 3^2) = sqrt(73), by the Pythagorean Theorem. That's approx. 8.54.
You could also leave your answer in the form √(8^2 + 3^2).
Why?
Because if you draw a line from A to D to make a triangle AED, then triangle all angle add up equal 180.
