Question

if the ratio of measure of two adjecent angles of a parallelogram is 1:2 find the measure of all angles of parallelogram.​

Answer 1

Answer:

ratio = 1:2

let ratio be 1x and 2x

1x+2x=180

3x=180

x=180/3

x=60

1x=60

2x=120

1 Answeri. Let ABCD be the parallelogram.

1 Answeri. Let ABCD be the parallelogram.The ratio of measures of two adjacent angles of a parallelogram is 1 : 2.

1 Answeri. Let ABCD be the parallelogram.The ratio of measures of two adjacent angles of a parallelogram is 1 : 2.Let the common multiple be x.

1 Answeri. Let ABCD be the parallelogram.The ratio of measures of two adjacent angles of a parallelogram is 1 : 2.Let the common multiple be x.∴ ∠A = x° and ∠B = 2x° ∠A + ∠B = 180° [Adjacent angles of a parallelogram are supplementary]

1 Answeri. Let ABCD be the parallelogram.The ratio of measures of two adjacent angles of a parallelogram is 1 : 2.Let the common multiple be x.∴ ∠A = x° and ∠B = 2x° ∠A + ∠B = 180° [Adjacent angles of a parallelogram are supplementary]∴ x + 2x = 180.∴ 3x = 180.
