The exercise is basically asking: how much do we have to add to x to get y?

If you look at the table, the y value is always 4 more than the correspondent x value.

So, in order to get y, you must add 4 to x.

$y=x+4$

Answer:

x = 4

8(4) - 2 = 30

15(4) = 60

All triangles equal 180 degrees and there is already a right angle. 60 plus 0 is 90, and 90 plus 90 (or 90 times 2) is 180

60 + 30 = 90

90 + 90 = 180
