$209.9$ feet

Work Step by Step

We can use the tangent of the triangle to solve for the angle. Since, $\tan \theta= \dfrac{Opposite}{Adjacent}$ $\tan 63^{\circ}= \dfrac{h_1}{330} $ and $\tan 53^{\circ}= \dfrac{h_1}{330} $ Simplify after subtracting the difference: $ h_1=330 \tan 63^{\circ}-330 \tan 53^{\circ} =209.9$ feet
