## Trigonometry 7th Edition

$a \approx 11$ cm
1. Solve for the angle $C$ $C + 48 + 54 = 180$ $C + 102 = 180$ $C = 78˚$ 2. Solve for $c$ $\frac{a}{sin(52)} = \frac{14}{sin(78)}$ $a = \frac{14sin(52)}{sin(78)}$ $a = \frac{11.03...}{0.978...}$ by GDC / calculator $a = 11.2786...$ cm $a \approx 11$ cm
