Question 1113447
<br>
You didn't write the problem correctly; and the other tutor didn't recognize what problem you were TRYING to work.<br>
The problem is about the Pythagorean Theorem; so the statement of the problem should talk about c^2 -- not just c.<br>
{{{c^2 = 17^2 + 19^2}}}
{{{c^2 = 289+361 = 650}}}
{{{c = sqrt(650) = 25.5}}} rounded to the nearest tenth.
