[tex]ZA=13.42m[/tex]
Explanation:
Hello! Remember you need to write complete questions in order to get good and exact answers. Here you haven't proviced any diagram, so I'll assume you are providing the measures of the sides of a right triangle, so we need to find the hypothenuse. The figure below shows the representation of this problem. Therefore, if we call the hypothenuse [tex]ZA[/tex], then by the Pythagorean theorem:
[tex]ZA^2=6^2+12^2 \\ \\ ZA=\sqrt{6^2+12^2} \\ \\ ZA=6\sqrt{5} \approx 13.42m[/tex]
