Question

please answer fastly​

Answer 1

Answer:

total angle of a square= 90*4

=360

ratio=3:4:5:6

sum=3+4+5+6

=18

1st=$\frac{3}{18} 360$

=20 * 3=60

2nd=$\frac{4}{18} 360$

=20*4=80

therefore 3rd=20*5=100

and 4th = 20*6= 120

--> 60+80+100+120=360

Answer 2

Step-by-step explanation:

19)

sum of the angle in a quadeilateral is 360 degree

3x:4x:5X:6X= 360

3+4+5+6/360=X

18/360=20

3*20=60

4*20=80

5*20=100

6*20=120

3:4:5:6=60:80:100:120

20)

angle dab=56 Degree

…therefore

angle dbc= 56 Degree

hope you got the ans

have a great day
