Question
The ratio of the angles of a quadrilateral is 3:2:7:8.
What is the sum of the largest and the smallest angle?Solution
ATQ,
Given: Ratio of angles = 3 : 2 : 7 : 8 Sum of angles in a quadrilateral = 360° Let angles be: 3x, 2x, 7x, 8x Total = 20x = 360 ⇒ x = 18 Angles: 3x = 54°, 2x = 36°, 7x = 126°, 8x = 144° Smallest = 36°, Largest = 144° Sum = 36 + 144 = 180⁰
