Question
In Exercises 5-24, use the Law of Sines to solve the triangle.Round your answers to two decimal places.$A\ =\ 120^{\circ}$,$B\ =\ 45^{\circ}$,$c\ =\ 16$
Step 1
We know that the sum of the angles in a triangle is 180 degrees. So, we subtract the measures of angles A and B from 180 degrees to find angle C. \[C = 180^{\circ} - A - B = 180^{\circ} - 120^{\circ} - 45^{\circ} = 15^{\circ}\] Show more…
