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,
Let the angles be 'y', '2y', '7y' and '8y' respectively.
Sum of all the angles in a quadrilateral = 360⁰
So, y + 2y + 7y + 8y = 360
Or, 18y = 360
Or, y = 20
Therefore, required sum = y + 8y = 9y = 9 × 20 = 180⁰
564.932 + 849.029 – 425.08 = 612.095 + ?
999.99 + 99.99 + 99= ?
