Question

An angle of a parallelogram is 30° less than its adjacent angle.find the measure of all its angle.

Answer 1

Step-by-step explanation:

Let the adjacent angle be x.

Therefore, the other angle is x- 30°.

x+ x - 30° = 180°[Sum of adjacent angles is supplementary]

2x = 180° + 30 °

x = 210°/2

x = 105°

Thus the angles are 105°,75°,105°,75°.
