Step-by-step explanation:

CD is an angle bisector and divides the opposite side into segments which are proportional to the other 2 sides, that is

$\frac{BC}{AC}$ = $\frac{BD}{AD}$ , substitute values

$\frac{4}{3}$ = $\frac{x}{2.25}$ ( cross- multiply )

3x = 9 ( divide both sides by 3 )

The present value of an ordinary annuity of $350 each year for five years, assuming an opportunity cost of 4 percent, is ___

liubo4ka [24]

We can calculate it by PVOA table.
PVOA means present value of an ordinary annuity.
PMT = $350
PMT means recurring payment.
time = 5 years and interest rate is 4%
So n = 5 and i = 4%
So we can calculate PVOA as

PVOA = PMT times (PVOA factor for n = 5 and i = 4%)
$= 350 * (4.452)$ (PVOA factor PVOA table)
$= 1558.2$
So present value is $1558.2
