HELP PLEASE!! 7. Which set of side lengths is from a right triangle? A. 4, 8, 10 B. 9, 10, 15 C. 6, 9, 14 D. 21, 28, 35

OpenStudy (treeclimber):

D because when finding the sides of a right triangle the legs when squared will equal the hypotenuse squared

OpenStudy (treeclimber):

so 21squared + 28squared =1225 and 35sqaured=1225

OpenStudy (treeclimber):

hope that helps
