So this is going Also, whencalculating angles and sides, be sure to carry the exact values through to the final answer. componendo and dividendo, \begin{align} Determine the length of to the nearest meter. Problem 1 Find the length of side X in the triangle below. Thus $\triangle ABC$ has sides $4,5$ and $6$cm. Round the altitude to the nearest tenth of a mile. It's going to be the same Solving for\(\gamma\) in the oblique triangle, we have, \(\gamma= 180^{\circ}-35^{\circ}-130.1^{\circ} \approx 14.9^{\circ} \), Solving for\(\gamma'\) in the acute triangle, we have, \(\gamma^{'} = 180^{\circ}-35^{\circ}-49.5^{\circ} \approx 95.1^{\circ} \), \(\dfrac{c}{\sin(14.9^{\circ})}= \dfrac{6}{\sin(35^{\circ})} \quad \rightarrow\quad c= \dfrac{6 \sin(14.9^{\circ})}{\sin(35^{\circ})} \approx 2.7 \), \(\dfrac{c'}{\sin(95.1^{\circ})} = \dfrac{6}{\sin(35^{\circ})} \quad \rightarrow\quad c'= \dfrac{6 \sin(95.1^{\circ})}{\sin(35^{\circ})} \approx 10.4 \).
