Suppose you have a $ 4-off coupon at a fabric store. you buy fabric that costs 7.50 per yard. write an equation that models the total amount of money y you pay if you buy x yards of fabric. (write in slope intercept form)

angle efh= angle egh

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
