X=-53x+378, if you need explanation used ask me.
Answer:
1) a = 110
2) b = 65
3) c = 115 d= 65 e = 115
How I found the last one?
The whole thing equals 360.
d is equal to 65 so I added those together.
That equals 130. So i subtracted that from 360.
I got 230. Next, I divided that by 2 to get the final 2 angles.
