if the hypotenuse is 58cm, and one of the others legs is 42cm the answer would be 40cm
Explanation:
Here you have to use the formula
[tex] {a}^{2} + {b}^{2} = {c}^{2}[/tex]
Then you have to pose the formula in terms of one of the legs, so:
[tex] {a}^{2} = {c}^{2} - {b}^{2} [/tex]
[tex]a = \sqrt{ {c}^{2} - {b}^{2}}[/tex]
So when you change the letter for numbers you have that:
[tex]a = \sqrt{ {58}^{2} - {42}^{2} }[/tex]
a=40
