Angelique says that finding the absolute value of a number is the same as finding the opposite of the number. for example |-5|=5. explain her error

Absolute value is the distance from zero on the number line, not the opposite number. Otherwise, absolute value would be negative when it can't be. For example, the absolute value of 5 is 5, not -5.

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
