Which set of measurements forms a right triangle? Use the Pythagorean theorem: a2 + b2 = c2.

A) 10, 12, 15

B) 10, 13, 15

C) 9, 12, 15

D) 9, 11, 15

Step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
