Answer:
option (a) $6,240
Step-by-step explanation:
Given:
Purchasing cost of the equipment = $82,000
Estimated life = 5 years
Salvage value = $4,000
Revised expected life = 8 years
Now,
Depreciation per year =
therefore,
The accumulated Depreciation at the beginning of year 4
= Annual depreciation × years passed
= 15,600 × 3
= $46,800
Thus,
The book value at the beginning of year 4
= Purchasing cost - Depreciation
= $82,000 - $46,800
= $35,200
Now,
The remaining life = Revised estimated life - Years passed
= 8 - 3
= 5 years
therefore,
Depreciation expense =
=
= $6,240
Hence,
The correct answer is option (a) $6,240
Given that ∠B ≅ ∠C.
to prove that the sides AB = AC
This can be done by the method of contradiction.
If possible let AB =AC
Then either AB>AC or AB<AC
Case i: If AB>AC, then by triangle axiom, Angle C > angle B.
But since angle C = angle B, we get AB cannot be greater than AC
Case ii: If AB<AC, then by triangle axiom, Angle C < angle B.
But since angle C = angle B, we get AB cannot be less than AC
Conclusion:
Since AB cannot be greater than AC nor less than AC, we have only one possibility. that is AB =AC
Hence if angle B = angle C it follows that
AB = AC, and AB ≅ AC.
