Answer: HEY GUYS
Step-by-step explanation:
HLO
LET THE COMMON RATIO BE X
THAT MEANS
1ST ANGLE=4X
2ND ANGLE=5X
3RD ANGLE=6X
WE KNOW
PERIMETER OF TRIANGE(P)=SUM OF ALL SIDES
45=4X+5X+6X
OR 45=15X
OR 45/15=X
OR 3=X
SO X=3
FIRST ANGLE=4X=4*3=12CM
SECOND ANGLE=5X=5*3=15CM
THIRD ANGLE=6X=6*3=18 CM

Step-by-step explanation:
- Let the sides of the triangle be 4x,5x and 6x
- Perimeter of a triangle =sum of the length of its sides
=4x+5x+6x=15x
=45
- x=45/15
=3
Therefore, 4x=12cm
5x=15cm
6x=18cm
Sides of the triangle measures 12cm, 15cm and 18cm.
hope it helps......
