1 & 3 are supplementary angles

1 & 4 are vertical angles

1 and 5 are corresponding angles

1 and 8 are alternate exterior angles

Step-by-step explanation:

I'm a bit unsure about the first one, but I know the rest are correct :)

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
