Question

the equal angle of paralleolgram are in the radio 4:5 . Find all angles of the in parallelogram in degree .​

Answer 1

Answer:

Angles = 80°, 80°, 100°, 100°

Step-by-step explanation:

Opposite angles of a paralleogram are equal.

And sum of angles in a quadrilateral is 360°

Let the angles be x

4x + 5x + 4x + 5x = 360

18x = 360

x= 360/18

x = 20

All angles are

4x = 4 × 20 = 80°

4x = 4× 20 = 80°

5x = 5 × 20 = 100°

5x = 5 × 20 = 100°
