X is a 40 degree angle because you can see the straight line that is to the right of x and to the left of y. And if you look at it like it is a whole circle x is one one half which is 180 degrees so you subtract the 80 and 60 degrees from the 180 degrees and you get 40. So the answer is 40 degrees.

Equation: 

When adding or subtracting, you have to make sure they have a common denominator

So you have to multiply  by 



Since they both have the same denominator, you subtract



One thing to note is when subtracting, you DO NOT subtract the denominator, only the numerators

To reduce to the lowest terms, you need to find a common factor.
