a
Step-by-step explanation:
I think the answer is 2 and -15. Because 2 times - 15 is -30 and 2 and -15 can be added to -1.
The First Answer Should Be 2 Not Four
The Second Answer:
12 : x
4 : 21
Cross Multiply
4x = 252
x = 63
If angle ec is a bisector then angles Bec and ced are the same making them both 4x+1. we know a line segment equals 180°. so if we take the 11x-12 and add it to 2(4x+1) we end up with 19x-10=180. you add 10 to both sides and get 19x=190 then you divide by both sides. you'll end up with x=10. you plug In the 10 with aeb and aec and add them together to get 139°. if you're looking for the equation, it's 15x-11.
