Question

Find each angle of a parallelogram iftwo consecutie angles are in the ratio 1:3.​

Answer 1

Step-by-step explanation:

Given: Consecutive angles are in ratio 1:3

Let the angles be 'x' and '3x'

Now, Sum of Consecutive angles must be 180°

Hence, x + 3x = 180°

=》 4x = 180° =》 x = 45°

Also, Opposite angles of parallelogram are equal...

Hence angles are , 45°, 75°, 45° and 75°.
