Answer:

∡a has a vertical angle sibling of 40°, and vertical angles are always congruent.

∡b is the 3rd angle in a triangle, the other two are 40° and 90°, recall all interior angles in a triangle add up to 180°.

∡c is a linear angle, namely an angle on the same flat-line as another, and linear angles always add up to 180°.

Answer:

Step-by-step explanation:

I think what they are asking is to subtract the 3 tokens from 21 tokens he already has giving us 18. and since it says "Twice the number of tokens" I'm assuming you divide 2 from 18 giving you 9 tokens.

Edward invested $1600 in a savings account for 8 years. At the end of 8 years, his savings account had $1920 in it.

miss Akunina [59]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &\$1920\\
P=\textit{original amount deposited}\to& \$1600\\
r=rate\to r\%\to \frac{r}{100}\\
t=years\to &8
\end{cases}
\\\\\\
1920=1600(1+r8)\implies \cfrac{1920}{1600}=1+8r\implies \cfrac{6}{5}=1+8r
\\\\\\
\cfrac{6}{5}-1=8r\implies \cfrac{\frac{6}{5}-1}{8}=r\implies \cfrac{\frac{1}{5}}{8}=r\implies \cfrac{1}{40}=r
\\\\\\
0.025=r\implies r\%=100\cdot 0.025\implies r=\stackrel{\%}{2.5}$
