Answer:
See explanation
Explanation:
I'm assuming that it wants you to describe how you found x. Alright.
For the second question, we see this is a 180 angle, and we subtract the existing 60 degrees to get 120 degrees. Divide this by the coefficient of x ( 3 ) and we get 40 or x.
For the third question, we see the top and bottom are equal and the lines are reflective so (5x-45) = 55. We use alteration to change this to 5x = 100 or x = 20.
For the fourth question, BAD is 110, and 110 - 55 = 55 = 5x, so x = 11 since 5x = 55 and (5)(11) = 55.
