Question

An unknown variable x when multiplied by four numbers 2,3,4 and 11 gives the angle of a quadrilateral. Its value is

Answer 1

Answer:

2x+3x+4x+11x =21x

21x+x+x+x=360 degree (Angle sum property of quadrilateral)

24x=360 degree

x=360/24=15 degree

21*15 = 315 degree and all the three angles are equal they are 15 degree
