Answer 2

Question:-

The measures of two adjacent angles of a quadrilateral are in the ratio 5:4. Find the measure of each angles of the parallelogram ?

Answer:-

∴ Sum of adjacent angles of a parallelogram is 180°

Thus, let the angles be 5x and 4x............

∴ 5x + 4x = 180

9x = 180

x = 20°

The angles are 100° and 80°.

∴ Opposite angles of a parallelogram are equal.So, all the angles are 100°, 80°, 100°, 80°
