Using the Law of Cosines, we can solve for the missing angle:
cos(38°) = (12^2 + 18^2 - x^2) / (2 * 12 * 18)
0.7880 = (432 - x^2) / 432
339.216 = 432 - x^2
x^2 = 92.784
x ≈ 9.64
Therefore, the measure of x in the triangle is approximately 10 degrees.
What is the measure of x in the triangle below? Round to the nearest degree.
