Palace help me solve these two equations 14, 15
IrinaVladis [17]
14)

check the picture below... so.. is just a semi-circle and a rectangle, nothing fancy, get their area, sum them up.

15)

so... the voter turnout, is referring to, what's the percentage that voted, which year has the highest percentage... well, we simply check the percentage of the value provided from the total eligible voters, keeping in mind that, all eligible voters are the 100%

so.. for 1944

\bf \begin{array}{ccllll}
amount&\%\\
------&----\\
86,607,000&100\\
47,976,670&x\\
\end{array}\implies \cfrac{86,607,000}{47,976,670}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 47,976,670}{86,607,000}\implies x\approx 55.39583405498

for 1984

\bf \begin{array}{ccllll}
amount&\%\\
-----&-----\\
167,727,000&100\\
92,659,000&x
\end{array}\implies \cfrac{167,727,000}{92,659,000}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 92,659,000}{167,727,000}\implies x\approx 55.2439380660239

I need help solving this plz
Mamont248 [21]
We can rewrite cot(45^{\circ}+2\theta) as tan(90^{\circ}-(45^{\circ}+2\theta) \Rightarrow cot(45^{\circ}+2\theta) equals to tan(45^{\circ}-2\theta).

Now we need to take an arctan of both sides.

\theta = 45^{\circ}-2\theta+180n^{\circ}&#10;\\3\theta = 180n^{\circ}+45^{\circ}&#10;\\\theta = 60n^{\circ}+15^{\circ}&#10;\\\theta = 15^{\circ}

Your answer is 15^{\circ}.
