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 = 41.9°, a = 187.9, and b = 248.6. sin B = (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 B₁ 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 A1B1C1 and triangle A2B2C2. Solve the first triangle: A₁B₁C₁ ZC₁ = and C1 = Solve the second triangle: A2B2C2 LC₂ = and c₂ =
