skeeter's = 66 + has a variable, but it should be easy to calculate from what skeeter did. BD (what skeeter called a) can be calculated from the law of sines or law of cosines because all the other sides and angles in triangle ABD are known, and it is about 0.813. The lengths of 1 are made up, but if you call them x, BD would be about 0.813x, and the calculations for the angles would be the same. Then CD (what skeeter called b) can be can be calculated from the law of cosines with BD, BC, and angle CBD known, and it is about 0.503. Then angle CDB can be calculated from the law of sines or law of cosines, and it is about 84 degrees, making x about 150 degrees. Angle C would have to be 66 degrees. However, then I did BD/sin(66) = BC/sin(84) to check my work, and they weren't equal. What did I do wrong?
