Describe the nature of the roots for this euation 3x^2-2x+1=0 a. two real, rational roots b. two real, irrational roots c. two complex roots d. one real, double root

This is the one real double root.  

EDIT: WRONG ANSWER, IT'S TWO COMPLEX ROOTS. Sorry.

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
