Since you have a angle number of 23 and you see the tiny square that means it’s equal to 90 up top and add 23 and 90 together and then subtract that by 180 to get all 3 angles in the triangle and then just use that to find the other line that’s 180.
Answer:
Table is attached
Step-by-step explanation:
We are given equation as

We will complete each column
First column:
we are given x=2 and we have to find y



Second column:
we are given y=3 and we have to find x



Third column:
we are given x=6 and we have to find y



Fourth column:
we are given x=0 and we have to find y



Fifth column:
we are given x=3 and we have to find y



Sixth column:
we are given y=0 and we have to find x



Seventh column:
we are given y=8 and we have to find x



now, we can complete table
3x + 4 = 2x + 2
3x - 2x = 2 - 4
x = -2
