The angle of elevation from a point on the ground to the top of a pyramid is \( 34 ^ { \circ } 40 ^ { \prime } \) . The angle of elevation from a point \( 115 \) feet farther back to the top of the pyramid is \( 12 ^ { \circ } 50 ^ { \prime } \) . Find the height of the pyramid.
What is the height of the pyramid? \( \square \) ft
(Round to the nearest integer.)
