Question
Measure of 2 angles of a quadrilateral are 110 and 100, remaining angles are equal. Find the angles.
Solution.
• Let the two equal angles be x.
• Other two angles are 100 and 110.
Sum of all angles in a quadrilateral = 360
⤇ 100 + 110 + x + x = 360
⤇ 210 + 2x = 360
⤇ 2x = 360-210
⤇ 2x = 150
⤇ x = 150/2
⤇ x = 75
⤖ Therefore the two equal angles are 75 degree.
