A rectangle has a perimeter of (12+8y). If one side of the rectangle is (4x-2y), write an expression of the other side.

ziro4ka [17]

P = 2(l+w)

substitute for P and l

12+8y = 2 (4x-2y+w)

distribute

12+8y = 8x -4y +2w

solve for w

subtract 8x from each side

12 +8y -8x = -4y+2w

add 4y to each side

12 +12 y -8x = 2w

divide by2

6 +6y-4x =w

the other side is 6+6y-4x

Wewaii [24]

We know that:

$\sin (\theta_1)=-\frac{12}{13}$

There is also an interesting property that relates the sine and the cosine of an angle:

$\sin ^2(\theta_1)+\cos ^2(\theta_1)=1$

We can find the cosine of theta using this equation:

$\begin{gathered} \cos ^2(\theta_1)=1-\sin ^2(\theta_1) \\ \cos (\theta_1)=\sqrt{1-\sin^2(\theta_1)} \\ \cos (\theta_1)=\sqrt[]{1-(-\frac{12}{13})^2} \\ \lvert\cos (\theta_1)\rvert=\sqrt[]{1-\frac{144}{169}}=\sqrt[]{\frac{25}{169}} \\ \lvert\cos (\theta_1)\rvert=\frac{5}{13} \end{gathered}$

Since theta is in the third quadrant then its cosine must be a negative number so:

$\cos (\theta_1)=-\frac{5}{13}$
