x = 21.19

Step-by-step explanation:

For this problem, we can apply the pythagorean theorem for right triangles.  That equation is:

a^2 + b^2 = c^2

Where side a is 7 and side b is 20 and the hypotenuse c is x.

(7)^2 + (20)^2 = c^2

49 + 400 = c^2

449 = c^2

21.19 = c

Hence, the value of the hypotenuse x is 21.19.
