4-3=1 and 5-4= 1 so it's 4
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.
Answer:
We do not have the equation for the part B, so we can not aswer it correctly.
But i will give a general answer.
We could have infinite answers always when we have more variables than linear independent equations:
This is, if we have one variable, x, we can have infinite solutions if we have no equations (or equations with no restrictions for our variable)
So if we have an equation like:
x*4 = √16*x
you can see that both sides of the equation are exactly the same, so this equation actually does not have any value, and x could take infinite different values and the equation will remain true.
If we have two variables, x and y, we will have infinite solutions if we have only one equation:
y = a*x + b
We have infinite pairs (x, y)
