x is hypotenuse if a perpendicular line is constructed at the base midpoint


6=x*cos(θ), 0<θ<90 degrees if vertex is above base

or x=6/cos(θ)

θ is an angle symbol used in trigonometry. if y>0 then just from Pythagorean theorem. x =hypotenuse side = square root (6^2+y^2) where y is length of perpendicular bisector of base. As can be shown, cos(θ)=6/(square root(6^2+y^2)
