Step-by-step explanation:
Given:
The measure of two adjacent angles of a parallelogram is in the ratio 3 : 7.
To find:
Measure of angles of the parallelogram.
Solution:
Let the angles be:
- 3x, 2x.
We know,
- Adjacent angles in a parallelogram are supplementary.
⇒ 3x + 2x = 180°
⇒ 5x = 180°
⇒ x = 180°/5
⇒ x = 36°
Angles are,
- 3x = 108°
- 2x = 72°
Measure of each angle:
- Opposite angles are equal in a parallelogram.
So all the angles are:
- 108°,72°,108°,72°
