The measure of the angle ∠ABD is 64 degrees

<h3>How to determine the measure of the angle?</h3>

From the question, we have the following parameters:

Ray BA bisects ∠CBD

∠CBD = 5x + 18

∠ABC = 3x - 2

Because of the bisection, we have

∠ABC = ∠ABD

∠ABC * 2 = ∠CBD

Substitute the known values in the above equation, so, we have the following representation

(3x - 2) * 2 = 5x + 18

Open the brackets

6x - 4 = 5x + 18

Evaluate the like terms

x = 2

Recall that

∠ABC = ∠ABD

So, we have

∠ABD = 3x - 2

This gives

∠ABD = 3 x 22 - 2

Evaluate

∠ABD = 64

Hence, the angle is 64 degrees

Find how long it takes a $ 900.00 investment to earn $ 120.00 in interest if it is invested at 6% compounded annually.

atroni [7]

So, we know the earned interest is 120, and we know the original deposited amount is 900 bucks, so, the accumulated amount will then be 900 + 120 or 1020 bucks.

$\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\to &\$1020\\
P=\textit{original amount deposited}\to &\$900\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{annually, thus once}
\end{array}\to &1\\
t=years
\end{cases}$

$\bf 1020=900\left(1+\frac{0.06}{1}\right)^{1\cdot t}\implies \cfrac{1020}{900}=(1.06)^t\implies \cfrac{102}{90}=(1.06)^t
\\\\\\
log\left(\frac{102}{90} \right)=log(1.06^t)\implies log\left(\frac{102}{90} \right)=t\cdot log(1.06)
\\\\\\
\cfrac{log\left(\frac{102}{90} \right)}{log(1.06)}=t\implies 20.92 \approx t$

CD = 13

6x - 5 = 4x + 1, combine like terms to get

2x = 6, divide 6 by 2

x=3, plug it in...

CD= 4(3)+1, which is 12 + 1

CD = 13
