To find the missing side length we need to use the Pythagorean theorem:
[tex]c^2=a^2+b^2[/tex]
Where a and b are the legs of the triangle:
[tex]\begin{gathered} a=60 \\ b=63 \end{gathered}[/tex]
We substitute this to find the hypotenuse c (the missing side)
[tex]\begin{gathered} c^2=60^2+63^2 \\ c^2=3600+3969 \\ c^2=7,569 \end{gathered}[/tex]
Now, we take the square root of both sides of the equation:
[tex]\begin{gathered} \sqrt[]{c^2}=\sqrt[]{7,569} \\ c=87 \end{gathered}[/tex]
Answer: 87m
