Question

One angle of a quadrilateral is of 1080 and the remaining three angles are equal. Find each of the three equal angles.

Answer 1

Answer:

84°

Step-by-step explanation:

Let each of the three equal angles be x°.

Now, sum of angles of a quadrilateral = 108°

⇒ 108° + x° + x° + x° = 360° ⇒ 3x° = 360° – 108°

x° = 252°/3

⇒ x° = 84°

∴ x° = 84°

Hence, each of the three equal angles is 84°.
