Answer :
ANSWER
[tex]c\approx4.8[/tex]EXPLANATION
To answer this question, we have to first find the measure of the third angle,
The sum of angles in a triangle is 180 degrees, which means that:
[tex]\begin{gathered} Now, we apply the sine rule:[tex]\frac{\sin A}{a}=\frac{\sin C}{c}[/tex]This means that:
[tex]\begin{gathered} \frac{\sin50}{4}=\frac{\sin 68}{c} \\ \Rightarrow c=\frac{4\cdot\sin 68}{\sin 50} \\ c\approx4.8 \end{gathered}[/tex]That is the value of c to the nearest tenth.
