What is the length of the missing leg in the triangle below?

We need to know the known side lengths to answer the question but I'll do my best to help you answer the question.

Step-by-step explanation:

Square the hypotenuse and subtract the answer by the square of the known leg. The square root of the answer will be the missing leg.

Pythagorean theorem is a²+b²=c² to find the hypotenuse.

But in this case, sense you are trying to find the length of a leg, it is c²-a²=b² (c is the hypotenuse length and a is the known leg length).

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✌✌✌
