**Henry**, Thursday, April 14, 2011 at 12:34pmtan23 = Y/X,

Y = Xtan23,

tan43 = Y/(X-.25).

Y = (X-0.25)tan43.

y = Xtan23 = (X-0.25)tan43,

Xtan23 = (X-0.25)tan43,

Xtan23 = Xtan43-0.25tan43,

0.4245X = 0.9325X-0.2331,

0.4245X-0.9325X = -0.2331,

-0.508X = -0.2331,

X = 0.4589 Miles.

y = 0.4589tan23 = 0.1948 miles.

Y = 0.1948mi * 5280ft/mi = 1029 Ft.

= Height of mountain.
