Question

4. The angles of a quadri lateral are in the
ratio 3:4.5:6. Find their measure.​

Answer 1

Answer: 60,80,100,120

Step-by-step explanation:

sum of all angles in a quadrilateral = 360 degrees

3+4+5+6 = 18

3/18×360=60 degrees

4/18×360=80 degrees

5/18×360=100 degrees

6/18×360=120 degrees

60,80,100,120 degrees

Answer 2

LET ANGLES =x

angles = 3x, 4x, 5x, 6x

sum of angles of quadrilateral = 360

therefore, 3x + 4x + 5x + 6x = 360

18x = 360

x = 20

so, angle one= 3x = 3*20=60

second angle=4x=4*20=80

third angle=5x=5*20=100

fourth angle=6x=6*20=120
