A 14-foot tree casts an 18-foot shadow. Find the angle of elevation from the tip of the shadow to the top of the tree. Round the answer to the nearest tenth.
+33666 The tangent of the angle is given by 14/18, so the angle is tan-1(14/18).
$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left({\frac{{\mathtt{14}}}{{\mathtt{18}}}}\right)} = {\mathtt{37.874\: \!983\: \!651\: \!098^{\circ}}}$$
Angle of elevation = 37.9° to the nearest tenth of a degree.
