12-16.

One angle of a triangle measures 70° and the opposite side has length of 37.2 feet. Another angle of the triangle measures 30°. Find the measures of the remaining angle and the two remaining sides of the triangle. Homework Help ✎

The sum of the angles in a triangle is 180°.

Use the Law of Sines to calculate the remaining side lengths.

$\frac{\text{sin}(70\degree)}{37.2}=\frac{\text{sin}(30\degree)}{x}$
