comment Quadratic equation formula for a,b,c from 3 points
@Mick - When working with my students I make an effort to help them not get hooked on the variable designations. I was clear in the answer I posted that OP need to be aware of that.

comment How can I find the lenght of the third side of any triangle
@NickH - this isn't a math problem, it's a surveying issue. OP wants to know how to physically measure that angle. The distance is anecdotal. I mean, with no angle, you know, there's no solution. He wants ideas how to measure the angle in the field. I assume without the expensive equipment. +1 by the way.

comment Find the equation of the parabola with its vertex on the line $2y-3x=0$?
If the axis of symmetry is parallel to the X axis, we're talking x=y^2, not the usual y=x^2. That's a start.
