At this rate, Brian plans 10/162 of his shirt.

The speed for which Brian iron the shirts is given by

        \frac{2}{9}/\frac{18}{5} = \frac{x}{1}

Cross multiply to get

        \frac{2}{9} =\frac{18}{5}x

Multiply both sides by 5/18 to solve for x.

         \frac{10}{162} = \frac{5}{31}

Find the exact values of cos 3 pi/4 radians sin 3 pi/4 radians.
Liula [17]
If you consult the unit circle, you will see that:

cos(\frac{3\pi}{4}) = -\frac{\sqrt{2}}{2}\\\\sin(\frac{3\pi}{4}) = \frac{\sqrt{2}}{2}

3pi/4 in degrees is 3pi/4 * 180/pi = 3/4 * 180 = 135 degrees. And please refer to the attachment to how you can obtain the values above.

Now, lets multiply it together.

-\frac{\sqrt{2}}{2} \cdot \frac{\sqrt{2}}{2} =\\\\-\frac{2}{4} =\\\\ \boxed{\bf{-\frac{1}{2}}}

So, <span>cos(3pi/4)sin(3pi/4) = -1/2</span>
