Question

In ️JKL, l=880 inches,

Answer 1

Answer:

816 inches

Explanation:

Let's go ahead and sketch the said triangle as shown below;

Let's go ahead and find the measure of $\begin{gathered} \angle J+\angle K+\angle L=180\ldots\ldots(\text{ sum of angles in a triangle)} \\ 63+11+\angle L=180 \\ \angle L=180-63-11 \\ \angle L=106^{\circ} \end{gathered}$We can go ahead and find the length of j using sine rule;

$\begin{gathered} \frac{l}{\sin L}=\frac{j}{\sin J} \\ j=\frac{l\sin J}{\sin L}=\frac{880\times\sin 63}{\sin 106}=816\text{ inches} \end{gathered}$
