None of these!
Step-by-step explanation:
x + y + z = x + y + z only over here
First you write what the vectors are, then you subtract z from w by subtracting their corresponding values <-4-3,1-4>= <-7,-3>, then to get subtracting the next answer you subtract w from z which is <3--4,4-1> = <7,3>
Sum of angle in a triangle is 180, so 33+70+x=180
x=77
x and y are vertical angles so y=77
