Answer:
The first unknown number is 10 the second is 20 and the third is 60
Step-by-step explanation
Since there is six numbers you have to multiply 25 times 6 = 150
Then 15+15+30=60
150-60= 90
10+20=30
30 times 2 equals 60
30+60=90
90+60= 150
150 divided by 6 = 25

Step-by-step explanation:
perimeter is to add all sides
73m= 16+B+C
{ use algebra}
C is a, B is twice C, hence 2a
a+2a(+16)=73
3a=73-16= 57
3a=57, divide
a= 19
B=19×2= 38m
C=19m
C is 19m
