1. The problem statement, all variables and given/known data the question is Find the measure of the indicated angle, to the nearest tenth of a degree. Heres a picture of the question. (sorry for the bad quality) http://img107.imageshack.us/img107/7002/mathproblem2bb2.jpg [Broken] ok for c) and d) I've applied what I've learned during the lesson, which was sin and cosin laws to try and solve this question...because this question is based on that lesson. and I just can get the same answer as the answer in the back of the book. for c i got the answer of 105.4 degrees... which makes absolutely no sense because the unknown angle is a acute angle, and the actual answer is 20.6 degrees. for d I got 1.9 degrees, but the actual answer is 7.8 degrees. could somebody provide me with a step by step instruction on solving this problem please? edit: for question d, the unknown angle is on the smaller triangle.
