Answer:
20 dollars
Step-by-step explanation:
I think 20+20+20=60 then 60-40=20
If we know that the WHOLE angle added is 105 and only part is 75 you need to subtract the whole angle and subtract from part of the whole angle.
105-75=30. You get 30 And that’s you answer!
Picture to help with your understanding.
Well let’s make it a decimal.
.75 = .84 + Y
So if .84 is more than .75 then subtract
.75 from .84 and you have your answer then convert to fraction
3/4 with the main number divide it
