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?
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)2In this right triangle, the legs are equal, and the hypotenuse is 10.(leg)2 + (leg)2 = (10)22 times (leg)2 = 100Can you take it from there ?

The perimeter of an equilateral triangle is 90 inches If a pentagon were constructed with each side being 2 inches longer than each side of the triangle how many inches would the total perimeter of?
Solve the problem in stages:Solve for the length of the triangle side.Perimeter = sum of all the sides. As equilateral, all sides equal so 3 x side_length = 90 inside_length = 90in / 3 = 30in.Pentagon side is triangle_side + 2in, thus Pentagon_side = 30in + 2in = 32inThere are 5 sides to a pentagon, each 32in long, so its perimeter is 5 x 32in = 160in.
