Me !me measure the diagonal of a triangle. so stressed. all i can tell u is that one side is 11 inches and the other 2 are 8 inches. it has a right angle. !

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✌✌✌
