Question

The angles of quadrilateral are in ratio 3:4:5:6. Find smallest angle.​

Answer 1

Step-by-step explanation:

let the angles be 3x,4x,5x,6x.

we know that angle sum oropety of quad =360.

ATQ

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

18x=360

x=360/18

x=20

hence ,

first angle=3 x 20=60

second angle=4 x 20=80

third angle = 5 x 20=100

fourth angle = 6 x 20=120

therefore the smallest angle is first angle =60

Answer 2

let the samllenst angle be x the 3x+4x+5x+6x=360=18x=360=×=20 3x=3×20=60,4x=4×20=80,5x=5×20=100,6x=6×20=120 then the samallest angle be 60
