Answer:
< BCA = 70
Step-by-step explanation:
The complete central angle of a circle is 360 degrees. The given portion is 250 degrees.
What is left over? BOA = 360 - 250 = 110
Tangents always meet the radius at 90 degrees. Since there are two tangents <CAO = <BAO = 90 degrees.
So piecing it all together, the equation becomes
<BAO + CAO + BAO + ACB = 360
110 + 90 + 90 + <ACB = 360
290 + <ACB = 360
<ACB + 290 - 290 = 360 - 290
ACB = 70 degrees

<h3>What is investment?</h3>
An investment is an asset or item acquired with the goal of generating income or appreciation.
As, 4th Year Cash Flow
= Salvage Value + Expected End Year Net Cash Flow
= $1,200 + $12,500
= $13,700
Year Cash flow ($) PVF at 8% Present value ($)
0 37,500 1.000 -36,300
1 12,500 0.9259 11573.75
2 12,500 0.8573 10716.25
3 12,500 0.7938 9922.5
4 13,700 0.7350 10069.5
Net value 5982
Hence, net present value of machine is $5982
