\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad\qquad \qquad 
cos(\theta)=\cfrac{adjacent}{hypotenuse}\\\\
-------------------------------\\\\
\textit{the point on the graph is }\left( \stackrel{cosine}{-\cfrac{8}{17}}~,~\stackrel{sine}{\cfrac{15}{17}} \right)

now, keep in mind that, the hypotenuse is just the radius unit, so is never negative, so if the cosine is negative, that simply means it has to be the numerator, the 8 is negative, -8. that means

\bf cos(\theta )=\cfrac{\stackrel{adjacent}{-8}}{\stackrel{hypotenuse}{17}}\qquad \qquad sin(\theta )=\cfrac{\stackrel{opposite}{15}}{\stackrel{hypotenuse}{17}}


so, the adjacent is -8, the opposite side is 15, and the hypotenuse is 17, so just plug them in then

\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad
cos(\theta)=\cfrac{adjacent}{hypotenuse}
\quad 
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}
\\\\\\
% cotangent
cot(\theta)=\cfrac{adjacent}{opposite}
\quad 
% cosecant
csc(\theta)=\cfrac{hypotenuse}{opposite}
\qquad 
% secant
sec(\theta)=\cfrac{hypotenuse}{adjacent}

1. The three salespeople for a local advertising firm are Sara, Kenny, and Leila. Sara sold $3350 in ads, Kenny sold $1368, and
Dominik [7]

Answer:

\text{Fraction of Sara sold }= \dfrac{1675}{2587}

\text{Fraction of Kenny sold }= \dfrac{684}{2587}

\text{Fraction of Leila sold }= \dfrac{228}{2587}

Step-by-step explanation:

The three salespeople for a local advertising firm are sara, Kenny and Leila.

Sara sold total ads = $3350

Kenny sold total ads = $1368

Leila sold total ads = $456

First we calculate total sale of all three = 3350 + 1368 + 456 = $5174

We need to find fraction of total sale with each person sell.

\text{Fraction of Sara sold }=\dfrac{\text{Sara total sold}}{\text{Total sale by all three}}

\text{Fraction of Sara sold }=\dfrac{3350}{5174}\Rightarrow\dfrac{1675}{2587}\approx 64.75\%

\text{Fraction of Kenny sold }=\dfrac{\text{Kenny total sold}}{\text{Total sale by all three}}

\text{Fraction of Kenny sold }=\dfrac{1368}{5174}\Rightarrow\dfrac{684}{2587}\approx 26.45\%

\text{Fraction of Leila sold }=\dfrac{\text{Leila total sold}}{\text{Total sale by all three}}

\text{Fraction of Leila sold }=\dfrac{456}{5174}\Rightarrow\dfrac{228}{2587}\approx 8.8\%
