X=square root of y square +z square make z the subject of the formula

To make z the subject of the formula, you can manipulate the equation as follows:

X = √(y^2 + z^2)

Square both sides of the equation to eliminate the square root:

X^2 = (y^2 + z^2)

Rearrange the equation:

z^2 = X^2 - y^2

Take the square root of both sides to solve for z:

z = √(X^2 - y^2)

Therefore, z = √(X^2 - y^2) is the formula with z as the subject.
