what is the area of a right triangle whose height is x and hypotenuse is y?

OpenStudy (anonymous):

0.5($\sqrt{y ^{2}-x ^{2}}$*(x)

OpenStudy (anonymous):

A = 1/2(base)(height) the height is given which is your x. so, you have to find the base. in order to find the base, use the pythagorean theorem c^2 = a^2 + b^2 so, y^2 = x^2 + b^2 then, b = $\sqrt{y ^{2}-x ^{2}}$ Area = $(x/2)(\sqrt{y ^{2}-x ^{2}})$
