urgent ! will give look at the figure below. which of the following statements could be a step in a proof that vertical angles are congruent?

Option d is right

Step-by-step explanation:

Given is a figure showing two straight lines AB and CD intersect at P.

Angle APC is adjacent to CPB

Hence APC +CPB =180

Similarly angle DPB is adjacent to same angle CPB

Thus we have

DPB+CPB = 180

Comparing these two equations, we get

APC = DPB

Option d is right

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
