Hoi!
To solve this, let's use apply the Pythagorean Theorem.
Formula: [tex]a^2 + b^2 = c^2[/tex]
For a and b, we would plug in the values for the two known legs.
[tex]16^2 + 28^2 = c^2[/tex]
[tex]16^2 = 256
28^2 = 784
256 + 784 = 1,040[/tex]
Now we take the square root of 1,040
[tex] \sqrt{1,040} = 32.2[/tex]
Your answer is 32.2 :)
