Find the measure of

Answer :

Given consecutive angles of a parallelogram are in the ratio 1:3
Therefore, the two consecutive angles be x and 3x.
x + 3x = 1800 (sum of the interior angles on the same side of the transversal is 1800) 4x = 1800 x = 450 Therefore the two consecutive angles are 450 and 3(450) = 1350. Since the opposite angles of a parallelogram are equal. The measures of all four angles of a parallelogram are 450, 450, 1350 and 1350.
