I don't know the answer but my tip would be to split the shape the way I did it, find the lengths of each side, and then find the area for each individual shape.

Then add all the areas together.

What are the sine cosine and tangent of theta=7pi/4 radians

FrozenT [24]

Answer:

see explanation

Step-by-step explanation:

$\frac{7\pi }{4}$ is in the fourth quadrant

Where sin and tan are < 0 , cos > 0

The related acute angle is 2π - $\frac{7\pi }{4}$ = $\frac{\pi }{4}$

Hence

sin([ $\frac{7\pi }{4}$ ) = - sin( $\frac{\pi }{4}$ ) = - $\frac{1}{\sqrt{2} }$ = - $\frac{\sqrt{2} }{2}$

cos( $\frac{7\pi }{4}$ ) = cos( $\frac{\pi }{4}$ ) = $\frac{\sqrt{2} }{2}$

tan( $\frac{7\pi }{4}$ = - tan( $\frac{\pi }{4}$ = - 1
