Question

If angle of quadrilater are in the ratio of 1:2:3:4.find the measure now

Answer 1

Answer:

we know that the internal angles of a quadrilateral add up to 360 degree..

if all the angles of ratio have common factor,x,then,

the angles of quadrilateral are x,2x,3x,4 x .

so, x+2x+3x+4x=360

=10x=360

so, x=360/10=36

so the angles are 36, 72, 108 and 144 degree. .
