Question

3 angles of a quadrilateral are in the ratio 4:6:3.If 4th angle is 100°,Find the other 3 angle​

Answer 1

Answer:

let the angles in the ratio be 4x,6x and 3x.

therefore

4x + 6x + 3x + 100 = 360 ( as the sum of all the angles of a quadrilateral is 360 degree)

4x+ 6x + 3x = 260

13x = 260

therefore,x = 20 degree

4x= 4*20 = 80

6x= 6*20= 120

3x = 3*20= 60

Answer 2

Answer:

4x+6x+3x+100 =360

13x+100=360

13x=360-100

13x = 260

x= 20.
