The three angles of a triangle have measures angle A = x + 2y degrees, angle B = 6x - 5y degrees, and angle C = 8x + 3y degrees. Find x (in degrees).

In a triangle the 3 angles have to sum to 180 so add them up and equate them to 180:

x+2y + 6x-5y + 8x+3y = 180 when yo add them the y's will be gone....solve for x
