Answer 1

First, angles 2 and 5 will add up to 180. So add 2 and 5 together, set them equal to 180, and find x.

Answer 2

Angle 2 is x+50. Angle 5 is 4x-30. Add them together, make it = 180.

Answer 3

x + 50 + 4x - 30 = 180

Answer 4

Find x, then use the fact that angle 1 and 2 are vertical angles, which are equal, to find angle 1.

Answer 5

Show your work.... first step is to combine all the like terms:

x + 50 + 4x - 30 = 180

add together the x and 4x, and the 50-30.
