The answer is 106 degrees. This is because 22 degrees + 52 degrees + 106 degrees = 180 degrees, completing the angles.
Hope this helps!
I beleive that it would be C=n25
Step-by-step explanation:
I'm not sure if this is not complex enough but I'm just going by what I think this is.
You should put 4 as x, -3 as y and a as slope to make an equation :

then you can find the slope and the correct equation of the line :
the slope is :

so the equation of the line will be

D is true
hope this helps
