Question

1. The measures of two adjacent angles of a parallelogram are in the ratio 3:2 . Then the angles are ___________ respectively. *


108 degree, 72 degree
100 degree, 80 degree
72 degree, 108 degree
80 degree, 100 degree​

Answer 1

Answer:

The option a is correct

108 degree, 72 degree

Answer 2

Answer:

108°, 72°

Step-by-step explanation:

As the angles are adjacent in a parallelogram, their sum will be 180°(co-interior angles).

Now let the angles be 3x° and 2x°.

=> 3x + 2x = 180°

5x° = 180°

∴x = 180/5 => 36°

Thus, angles are 3x = 36(3) => 108°

2x° = 36(2) => 72°
