ANSWER

[tex]\begin{gathered} a)EXPLANATION

a) To find the measure of apply sine rule that states that:

Therefore:

[tex]\frac{\sin(Therefore, for the given triangle:[tex]\begin{gathered} \frac{\sin80}{6.17}=\frac{\sin (That is the measure of

b) To find c, we first have to find The sum of angles in a triangle is 180°.

Therefore:

[tex]\begin{gathered} Now, apply sine rule:[tex]\begin{gathered} \frac{\sin(That is the value of c.
