Let each of three equal angles be x∘. Now, sum of angles of a quadrilateral = 360∘ ⇒108∘+x∘+x∘+x∘=360∘⇒3x∘=360∘−108∘ ⇒x∘=252∘3 ∴x∘=84∘ Hence, each of the three equal angles is 84∘.
One angle of a quadrilateral is of 108∘ and the remaining three angles are equal. Find each of the three equal angles. Thinking Process: The sum of all the angles in a quadrilateral is 360∘, use this result and simplify it.
Three angles of a quadrilateral are equal and the measure of the fourth angle is 1200. Find the measure of each of the equal angles.
