What additional information would you need to prove

A

Step-by-step explanation:

We use the Hypotenuse Leg Theorem

When we know the hypotenuse and a leg of a triangle.

We know The Hypotenuse (TO) so we need to know A leg of the triangle which the only leg is TM and OR.

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✌✌✌
