1. the opposite angles of a parallelogram measure(x=30) and (2x-50).Find the measure of each angle of the parallelogram.

2. the ratio of two consecutive angles of a parallelogram is 2:3. find the measurement of the angles of a parallelogram.

3.the difference between the measure of two consecutive angles of a parallelogram is 80. find the measure of each angle of the parallelogram.

1. The opposite angles of a parallelogram are equal

Use that property to form an equation, (you are given the angles) and solve that equation

2. Consecutive angles of a parallelogram add up to 180°. Let the angles be 2x and 3x, form your equation and solve

3. Let one angle be x, then the other angle has to be 180-x

so solve x - (180-x) = 80
