Check the picture below.

so... notice "y", is also a vertical angle with the other side.

now, there are a total of 360° total in a circumference... so.... if the left-angle is 68, and the right-angle is also 68, because they're vertical angles, then the remainder is 360 - 68 - 68 which is 224.

now, the remainder has to be split evenly between the two remaing angles, "y" and her twin, thus each one takes half of 224, and thus "y" is half of 224.

68= 4x-2+30 (notice they are vertical angles)
68= 4x+28
40=4x
10=x

68+y= 180 (forms a straight angle)
y=112

Final answer: x=10, y=112

Adding and subtracting with negative numbers

First, recognize that adding and subtracting are, from one viewpoint, the same thing. Subtracting a number is the same thing as adding the negative of that number. For example, 4 – 12 is the same as 4 + –12 (which, because the order of terms doesn't matter with addition, is the same as –12 + 4). With that in mind, here are the rules for adding with negative and positive numbers:

If both numbers are positive, then the answer is positive.

If both numbers are negative, then the answer is negative.

If the numbers have different signs, the answer takes the sign of the higher number.

Subtracting a negative number is the same as adding the positive of that number. For example, 5 – –4 is the same as 5 + 4.

Multiplying and dividing with negative numbers if the numbers have different signs, the answer is negative.
