week 7 math post
categories: Math 10
in this triangle I have the A angle, and side AB, which is 42.2. We are trying to find the variable b on the AC side. After labeling I was trying to find the adjacent side. To do this I had to use COS. I had to go cos25 x 42.2 because the variable is on the top. the answer I got was 38.2.
in this triangle it was cos again and my formula was 50.2 over cos30. I had to reciprocate the variable and create a division question. my answer was 57.96
this triangle was cos once again, and in order to complete this I had to do cosX = 5 over 6. in order to isolate the variable I had to move X to make cos-1 (5/6). this gave 33.55
