Question

5. The measures of two adjacent angles of a parallelogram are in the ratio 3:2. Find the measure of each of the angles of the parallelogram​

Answer 1

Answer:

108° 72° 108° 72°

Step-by-step explanation:

Let the adjacent angles be 3x and 2x

In a parallelogram, the opposite angles are equal.

Therefore the angles will be: 3x, 2x, 3x and 2x

Sum of the angles of a parallelogram = 360°

3x + 2x + 3x + 2x = 360°

10x = 360

x= 36°

Therefore, the angles are:

3x = 108°

2x = 72°

3x = 108°

2x = 72°
