Question

The angles of quadrilateralare in the ratio 3:5:10:12 Find all the angles of the quadrilateral.

Answer 1

Answer:

Let the common ratio between the angles be x. Therefore the angles will be 3x 5x 9x and 13x respectively.As the sum of all interior angles of a quadrilateral is 360º ∴ 3x + 5x + 9x + 13x = 360º30x = 360ºx = 12ºHence the angles are3x = 3 × 12 = 36º5x = 5 × 12 = 60º9x = 9 × 12 = 108º13x = 13 × 12 = 156º

Answer 2

Answer:

let angles be x now add all four angles 3x+5x+10x+12x equal 360 now value of x is 12 put value so answers are 36,60,144,200
