Answers
Correct Question :
The measure of two adjacent angles of a parallelogram are in the ratio 3:2 find the measure of each of the angels of the parallelogram
Answer :
the angles of the parallelogram are 72° , 108° , 72° and 108°
Step-by-step explanation :
Given :
the measure of two adjacent angles of a parallelogram are in the ratio 3:2
To find :
the measure of each angle.
Solution :
Let the adjacent angles be
- 3x
- 2x
In a parallelogram, the adjacent angles are supplementary angles.
i.e., The sum of the measures of the adjacent angles = 180°
➙ 3x + 2x = 180°
➙ 5x = 180°
➙ x = 180°/5
➙ x = 36°
⇒ 2x = 2 × 36° = 72°
⇒ 3x = 3 × 36° = 108°
The adjacent angles of the parallelogram are 72° and 108°.
Also, in a parallelogram the measure of the opposite angles are equal.
Hence, the angles of the parallelogram are 72° , 108° , 72° and 108°
