Given:
The complex number is:
To find:
The argument of the given complex number.
Solution:
If a complex number is 
, then the argument of the complex number is:
We have,
Here, 
and 
. So, the argument of the given complex number is:
Therefore, the argument of the given complex number is .
Sinx = cosb => x + b = 90 <=> b = 90 - 47 = 43o
1, yes by the rule of S:A:S
2. yes by the rule of aas
5. yes by the rulee of side-hypnotuse-angle
4 yes by side angle side
A. Using the straight-line depreciation method, we can
calculate for the depreciation using the formula:
d = (P – S) / n
Where,
P = present value
S = salvage value
n = number of life years
Substituting the given values:
d = ($465,000 - $45,000) / 15
d = $28,000
The depreciation for the first year was $28,000 and the
book value is $437,000.
B. Calculating for the book value at the end of eight
year:
BV (8) = $465,000 – 8 * $28,000
BV (8) = $241,000
<span>Since the equipment was sold at only $235,000 therefore
there was a loss of $6,000.</span>
<span>C. Chart of accounts is needed.</span>
