You have a coupon good for $5 off the price of any large pizza. you also get a 20% discount on any pizza if you show your student id. how much more would you pay for a large pizza if the cashier applies the coupon first?

ummm seems that u didnt post the attachement !

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.
