Question

what is measure of the largest angle of a quadrilateral whose angles are in ratio 3:4:5:6?​

Answer 1

Answer:

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

18x=360

x=20

largest angle will be 120

Answer 2

Answer:

we know quadrilateral=360

and sum of two opposite sides are 180

then a to q

ratio are given 3:4:5:6

sum of ratio = 3x+4x+5x+6 x=18 x

ist angle =360\18=20 *6=120

you do yourself in between

6th angle= 360\18*5= 40
