Answer 1

6.40 units

Explanation:

You can use the equation a^2+b^2=c^2 for this. C is the unknown and the hypotenuse.

In this case, 4^2+5^2=c^2.

16+25=c^2

41=c^2

sqrt{41}= c

Approximately 6.40312

Answer 2

Answer is 6.40 units

Explanation:

Pythagorean theorem

a^2+b^2=c^2

fill in the sides for a and b

4^2 + 5^2 = c^2

simplify

16+25 = c^2

41 = c^2

Sqrt both sides

c = 6.4
