B 17.5283 cm 14 cm 620 A 19 cm Now that we have added in the final missing side length, the only remaining unknown pieces of information are m./ B and m./C. These can be determined using the Law of Sines and/or other properties of triangles as you did in previous lessons. Go ahead and determine this missing information a. m/B = * degrees Preview sin (m/ B) * Try again. Look back at our previous work. The first step in the solution process is to write an equality like sin (62" ) 19 17.5283 and then solving for m/ B. Also, if you are entering any trigonometric expressions into your answer box, make sure you are entering them correctly. See the click to reveal note at the bottom of this question. b. m/C = * degrees Preview * Try again. Have you successfully completed part (a)? If you know m./ B, remember that the sum of the three interior angle measures in a triangle is always 180". Note that this question allows you to use trig functions that evaluate for angle measures in degrees.
