Find dy/dx using implicit differentiation ln(20+e^xy)=y

Two line segments are shown in the figure below. suppose that the length of the line along the x-axis is 6, and the length of the hypotenuse of the triangle is 10. what is the equation of the hypotenuse line (shown in red, below)?

Segment wx is shown explain how you would construct a perpendicular bisector of wx using a compass and a straightedge
