A brace for a shelf has the shape of a right traingle its hypotenuse is 10 inches long and the wo legs are equal in length how long are the legs of the traingle .need the formula please?

Answer 1

The only formula you need is one that we're sure you already know.

In every right triangle,

(leg-A)2 + (leg-B)2 = (hypotenuse)2

In this right triangle, the legs are equal, and the hypotenuse is 10.

(leg)2 + (leg)2 = (10)2

2 times (leg)2 = 100

Can you take it from there ?
