Vertical leg is 795 feet, and horizontal leg is 405 feet.

x, angle of elevation

, and you can find x, maybe needing to use calculator or trig table.

You could have chosen tangent function instead. Either way, you should find 63 degrees (to nearest whole number).

the monument is still ft away
but the height is ft so that
I have a right triangle.
