4x+2x+6 (which is ab plus bc)
6x+6 (the length of ac)
You have to isolate the a. Add fifteen to both sides of the equation, so it’s
2a=15-1
Then subtract 15 and 1, so then the quantity is 14
2a=14
Then divide 2 by both sides, and the answer is
a=7
45+2a=180. You should always try to write down an equation for problems like these. Subtract the 45 to both sides of the equal sign. This gets you 2a=135. Divide the 2 on both sides and you get a=67.5 degrees. I hope that i helped, enjoy
