Answer 1

`4√(5)`

Explanation:

We can use the Pythagorean Theorm, which states that the sum of the squares of both legs (sides touching right angle) equals the hypotenuse squared (side not touching right angle)

a^2 + b^2 = c^2, where a and b are the legs, and c is the hypotenuse. In this question, we are trying to find the hypotenuse.

we see that a = 4 and b = 8. We plug these values in to get

4^2 + 8^2 = 16 + 64 = 80 = c^2

80 = c^2 we take the square root of both sides to get

`c = √(80)`

we can simplify that since we can take 4^2 out of 80.

`c = 4√(5)`
