Hey You!

I believe there could be 2 answers to this question.

1. 6 dimes & 9 nickels. (60 + 45 = 105)

2. 1 quarter, 12 nickels, 2 dimes. (25 + 60 + 20 = 105)

Find the coordinates of the point P at an angle of 45 degrees on a circle of radius 4.5. Round your answer to 3 decimal places.

Varvara68 [4.7K]

$\bf sin(\theta)=\cfrac{y}{r}
\qquad 

% cosine
cos(\theta)=\cfrac{x}{r}\quad 
\begin{cases}
r=radius=hypotenuse\\
x=adjacent\\
y=opposite\\
\theta=angle
\end{cases}\\
-----------------------------\\
thus
\\\\

\begin{cases}
r=4.5\\
\theta=45^o
\end{cases}\implies 
\begin{cases}
sin(\theta)=\cfrac{y}{r}\to sin(45^o)=\cfrac{y}{4.5}\to 4.5\cdot sin(45^o)=y
\\\\
cos(\theta)=\cfrac{x}{r}\to cos(45^o)=\cfrac{x}{4.5}\to 4.5\cdot cos(45^o)=x
\end{cases}
\\\\
P\ is \ at\quad (x,y)$

the angle is in degrees, thus, when taking either sine or cosine, make sure your calculator is in Degree mode
