Question

If two adjacent angles of a parallelogram are in the ratio 1:3, then find its all angles

Answer 1

180/4 =45
one angle is 45
other angle is 180-45=135

Answer 2

Let the adjacent angles be x and 3x.

We know that, sum of the adjacent angles of a llgram is 180°

Therefore, x + 3x = 180°
=> 4x = 180°
=> x = 180°/4
=> x = 45°
And 3x =3 × 45° = 135°

Hence, the angles are 45°, 135°, 45° and 135°.
