Hie!! I will be solving the questions in the sequence of the attachments.

4. As line SU and TV are intersecting each other at O.

A.T.Q, ∠UOV = (7x - 4)°

∠SOT = 87°

Then, ∠UOV = ∠SOT {Vertically Opposite Angles}

$\rightarrow\sf{7x - 4=87}$

$\rightarrow\sf{7x =87+4}$

$\rightarrow\sf{7x =91}$

$\rightarrow\sf{x =\frac{91}{7}}$

$\rightarrow\boxed{\bf{x =13}}$

_______________________________________

5. radius = 17ft

circumference of circle = 2πr

$\rightarrow\sf{circumference=2\times\frac{22}{7}\times17}$

$\rightarrow\boxed{\bf{circumference=106.8ft}}$

_______________________________________

3. ∠1 and ∠2 - add to 180 (linear pair)

∠1 and ∠3 - equal (Vertically Opposite Angles)

∠3 and ∠4 - add to 180 (linear pair)

∠2 and ∠4 - equal (Vertically Opposite Angles)

_______________________________________

2. 160° + (6x - 16)° = 180° (linear pair)

$\rightarrow\sf{6x - 16 = 180-160}$

$\rightarrow\sf{6x - 16 = 20}$

$\rightarrow\sf{6x = 20+16}$

$\rightarrow\sf{6x =36}$

$\rightarrow\sf{x =\frac{36}{6}}$

$\rightarrow\boxed{\bf{x =6}}$

Sarafina is making monthly payments into an annuity. She wants to have $900 in the fund to buy a new convection range in six m

Oksi-84 [34.3K]

$\bf \qquad \qquad \textit{Future Value of an ordinary annuity}
\\\\
A=pymnt\left[ \cfrac{\left( 1+\frac{r}{n} \right)^{nt}-1}{\frac{r}{n}} \right]$

$\bf \begin{cases}
A=
\begin{array}{llll}
\textit{accumulated amount}\\
\end{array}\to &
\begin{array}{llll}
900
\end{array}\\
pymnt=\textit{periodic payments}\\
r=rate\to 8.4\%\to \frac{8.4}{100}\to &0.084\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{monthly payments, thus}
\end{array}\to &12\\

t=years\to \frac{6}{12}\to &\frac{1}{2}
\end{cases}
\\\\\\
900=pymnt\left[ \cfrac{\left( 1+\frac{0.084}{12} \right)^{12\cdot \frac{1}{2}}-1}{\frac{0.084}{12}} \right]$

solve for "pymnt"
