Question

find the measures of angles of quadrilatal ratio angles in 3:4:5:6​

Answer 1

let angles

3x 4x 5x 6x

add

(3+4+5+6)x=360 angle sum

18x=360

x=360/18 = 20

so ans is

60 80 100 120

Answer 2

here the measure of angle of quadrilateral is 3 :4 : 5 :6
they are 3x,4x,5x,6x
measure of quadrilateral is equal to 360 degree

3x + 4x+ 5x+ 6x=360
18x = 360
x = 360/ 18
x = 20

1st angle = 3x = 3×20=60°
2nd angle = 4x = 4×20=80°
3rd angle = 5x = 5×20=100°
4th angle = 6x = 6 × 20 =120°
60°,80°,100°,120° are the angle of given quadrilateral
