Given a right angle triangle
The hypotenuse = 29 cm
the length of one leg = 21 cm
Let the missing side = x
We will find x using the Pythagorean theorem as follows:
[tex]29^2=x^2+21^2[/tex]
Solve for x:
[tex]\begin{gathered} x^2=29^2-21^2=841-441=400 \\ \\ x=\sqrt[]{400}=20 \end{gathered}[/tex]
so, the answer will be:
The missing side = 20 cm
