One of the angles of the parallelogram is 30 degrees larger than the other, find the degree measures of all angles of the parallelogram.
A parallelogram has a sum of adjacent angles equal to 180.
Let one of the angles be equal to X0, then the other is equal to X + 30.
X + X + 30 = 180.
2 * X = 150.
X = 750, then the second angle is 75 + 30 = 105.
Answer: The angles of the parallelogram are 75.105, 75.105.
