Question
In Exercises 5-24, use the Law of Sines to solve the triangle.Round your answers to two decimal places.$A\ =\ 55^{\circ}$,$B\ =\ 42^{\circ}$,$c\ =\ \frac{3}{4}$
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 to find angle C. \[C = 180^{\circ} - A - B = 180^{\circ} - 55^{\circ} - 42^{\circ} = 83^{\circ}\] Show more…
