Math problem..

Trigonometric problem..
A car is facing a structure.  Its initial position is at a slanted distance from the top of the structure and a horizontal distance from the bottom (no lengths given), forming a 27 degree angle at the point that the car is set on.  The car drives 307 ft toward the structure and the angle expands to 38 degrees.  Find the height of the structure with this information.

h/x = tan(27)
h = xtan(27)

h/(x-307) = tan(38)
h = (x-307)tan(38)

xtan(27) = (x-307)tan(38)
xtan(27) = xtan(38) - 307tan(38)
x(tan(27) - tan(38)) = -307tan(38)
x = -307tan(38) / [tan(27) - tan(38)]
h = -307*tan(38)*tan(27) / [tan(27) - tan(38)]

That would equal -307, which can't be the height under any circumstances.
