Answer:
Hello! answer: 17
Step-by-step explanation:
Assuming this is the Pythagorean theorem our formula would be
a^2 + b^2 = c^2
meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...
15 × 15 = 225 8 × 8 = 64 225 + 64 = 289
the square root or the (number multiplied byitself that equals 289) is 17 because
17 × 17 = 289 so × = 17 I hope that helps!
It would be 75 after the sale. Hope it helps! :)
