Question
In Exercises 5-24, use the Law of Sines to solve the triangle.Round your answers to two decimal places.$B\ =\ 28^{\circ}$,$C\ =\ 104^{\circ}$,$a\ =\ 3\frac{5}{8}$
Step 1
We know that the sum of the angles in a triangle is 180 degrees. So, we subtract the measures of angles B and C from 180 degrees to find angle A. \[A = 180^{\circ} - B - C = 180^{\circ} - 28^{\circ} - 104^{\circ} = 48^{\circ}\] Show more…
