Question

the angels of a quadrilateral are in the ratio 3:4:5:6 ,, find their measures

Answer 1

let the angle are 3x,4x,5x,6x
a/q 3x+5x+4x+6x= 360
18x= 360
x= 20
angle are 60,80,100,120
please reply

Answer 2

let x be comman multiple
the sum of all angle of QUADRLATERAL is 360'
$3x + 4x + 5x + 6x = {360}^{0}$
$18x = 360$
$x = 2$
put the vale of x in 3x 4x 5x 6x
