Answer:
45,60,75
Step-by-step explanation:
One angle of a quadrilateral = 180 degree
The other angles are in
the ratio of =3:4:5
Sum of the ratio = 3+4+5
= 12 parts
1 part = 180/12
= 15
3:4:5
1 st angle ratio is 3=3*15 =45 degree
2 ND angle ratio is 4=4*15=60 degree
3 rd angle ratio is 5=5*15=75 degree
Verification :-
45+60+75+180=360 degrees
Total angle of a quadrilateral is always 360 degrees
