Answer:
Step-by-step explanation:
Assuming that's about a right triangle, the image attached shows a representation of this problem.
We use the Pythagorean Theorem to find the missing leg, which we are gonna call [tex]y[/tex]
[tex]29^{2} =18^{2}+y^{2}\\y^{2}=29^{2}-18^{2}\\y=\sqrt{841 - 324} \approx 22.7 \ cm[/tex]
Therefore, the leg MA measures 22.7 centimeters.
