Question 356491: Triangle ABC is inscribed in a semicircle of diameter a = 7 (see the figure). If x denotes the length of side AC, express the length y of side BC as a function of x. (Angle ACB is a right angle.)
x^2+y^2=7^2
y=?

You're on the right track, keep going.
x%5E2%2By%5E2=7%5E2
y%5E2=49-x%5E2
highlight%28y=sqrt%2849-x%5E2%29%29
