Question

two adjacent angles of a parallogram are in the ratio 1:3 find its angles​

Answer 1

Step-by-step explanation:

Therefore x = 45°. So, 1st angle = 1x = 45°. and 2nd angle = 3x = 45°× 3 = 135°.

Answer 2

Step-by-step explanation:

Let 1:3 be X and 3X

The angle between two adjacent angles is supplementary (180°)

so,

X+3X=180°

4X=180°

X=180°/4

X=45°

so,

X=45°

3X=135°
