Solve 12x - 6] > 10
{XIX <-8 or x> 2]
{xlx < -2 or x > 8}
{XI-2

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

i believe the answer is c.
