If you're trying to solve for y
-2y = 8
Divide -2 to both sides
Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4
-2y = 8
Divide -2 to both sides
Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4
Since vertical angles are equal you can put the same value to the opposite angles. Also, you were given a supplementary angle which are two angles added to 180 degrees. Of those 180 you were given 100. The angle next to the 100 degrees has a value of 80. With all this, you add all the angles together and put it equal to 180 which is what the angles of a triangle add up to. Then you combine like terms to get the value of X and just replace it for x. After that you just multiply and then add.
