one angle of a triangle is 3 times as large as another. third angle is twice the sum of the first two angles what is the measure of the largest angle . Please help

OpenStudy (johnweldon1993):

okay so theta1 = x theta2 = 3x theta3 = 2(theta1 + theta2) And now we know that the interior angles of a triangle add to 180...so x + 3x + 2(x + 3x) = 180 Can you solve this from here?
