Solve for h. rs + h^2 = l
Subtract rs from each side to isolate h:
rs - rs + h^2 = l - rs
Cancel the rs terms on the left side, and we get:
h^2 = l - rs
Take the square root of each side:
h = sqrt(l - rs)
Subtract rs from each side to isolate h:
rs - rs + h^2 = l - rs
Cancel the rs terms on the left side, and we get:
h^2 = l - rs
Take the square root of each side:
h = sqrt(l - rs)
