First. we use the Pythagorean theorem:
[tex]a {}^{2} + b {}^{2} = c {}^{2} [/tex]
Add the numbers in
[tex] {30}^{2} + {b}^{2} = {50}^{2} [/tex]
start simplifying
[tex] {b}^{2} = 1600[/tex]
[tex]b = 40[/tex]
So, the leg has a length of 40 mm.
[tex]a {}^{2} + b {}^{2} = c {}^{2} [/tex]
Add the numbers in
