Because the angle that is opposite 123 degrees it will equal 180. You do 180-123 which is 57 then the angle on the opposite side (angle x) the angle which is on the other side of it will be 57 degrees. To find the size of angle x you would have to do 180- 57 which is 123 degrees

Answer: 123 degrees

99 degrees

180 - 123 = 57
180 - 57 - 42 = 81
180 - 81 = 99

How do I find the slope, domain, range and y intercept of y=-2x

Natasha2012 [34]

Slope is defined as the rate of change, in this case the change in y with respect to x. In standard form for a binomial linear equation, y = mx + b. The constants m and b are the slope and intercept, respectively. For your equation, the slope is -2 and the intercept is 0. The domain (possible values of x) for this graph is (-∞, ∞) and the range (possible values of y) is also (-∞, ∞).
