In order for us to calculate the side lengths a and b we have to do the following: First calculate angle C = 180-(58+82). If we solve this we will get 40. Now using the sin rule we will have our 3 forms: a/sin58, b/sin82 and, 8.4/sin40.
To solve for a we have (8.4sin58)/sin40 = 11.08
To solve for b we have (8.4sin82)/sin40 = 12.94
Therefore the correct answer is Choice B) a = 11.08 and b = 12.94
I hope it helps, Regards.
