Answer:
60
Step-by-step explanation:
Well initial value is the starting amount or when x is 0
when x is 0 y is 60 hence 60 is the answer
We know that ∠1 equals ∠3, from that we can find x:
The sum of ∠1 and ∠2 must equal 180°:
Since we already know x, we can solve for y:
Result: x=10, y=6
Subtract 20 from 40 then divide by 10
C=2
