Answer
$$x \approx 145$$
Work Step by Step
1. Find the last angle.
$$102 ^{o} + 28^o + C = 180^o$$ $$C = 180^o - 102^o - 28^o = 50^o$$
2. Use the law of sines to calculate $x$:
$$\frac{sin \space 50^o}{x} = \frac{sin \space 102^o}{185}$$ $$x = \frac{sin \space 50 ^o}{sin \space 102^o} \times 185$$ $$x \approx 145 \space (Calculator)$$
