Solve for in the equation x2 - 2x - 35 = 0.

{-5, -7}

{5, -7}

{-5, 7}

{5, 7}

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 think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8
