1. the opposite angles of a parallelogram measure(x=30) and (2x50).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.

Reiny,
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 180x
so solve x  (180x) = 80

malo,
(180) because n(180) formula.. :)
