Remember, even if you enter an answer rounded to a set number of decimal places, if you use that number in a future calculation, you should use all of the decimal places reported on your calculator! Solve triangle ABC if ZA = 42.9", a = 186.2, and b = 249.4. sin B = 0.9117711317 vo (round answer to 5 decimal places) There are two possible angles B between 0' and 180° with this value for sine. Find the two angles, and report them so that ZB¡ is the acute angle. ZB1 = and ZB2 (round these and all remaining answers to 1 decimal place) Thus, two triangles satisfy the given conditions: triangle A, B,C1 and triangle A,B»C2. Solve the first triangle: A¡ B¡C1 ZC; = and Ci = Solve the second triangle: A2 B2C2 ZC2 = and C2
