Is the ordered pair a solution of y ≥ 2x − 5? a. (3, 1) b. (1, −4)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

both equations and proportions are better.
