Answer:
Area = 406
Step-by-step explanation:
First things first: Divide the shape
Here is how I did it:
21 x 16
14 x 5
Now solve:
21 x 16 = 336
14 x 5 = 70
Now add:
336 + 70 = 406
So the area is 406

Answer:
![cos(2\theta)=-\frac{7}{25}](https://tex.z-dn.net/?f=cos%282%5Ctheta%29%3D-%5Cfrac%7B7%7D%7B25%7D)
Step-by-step explanation:
we are given
![tan(\theta)=\frac{4}{3}](https://tex.z-dn.net/?f=tan%28%5Ctheta%29%3D%5Cfrac%7B4%7D%7B3%7D)
Firstly, we will draw triangle
Since, angle lies in third quadrant
so,
![sin(\theta)=-\frac{4}{5}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D-%5Cfrac%7B4%7D%7B5%7D)
![cos(\theta)=-\frac{3}{5}](https://tex.z-dn.net/?f=cos%28%5Ctheta%29%3D-%5Cfrac%7B3%7D%7B5%7D)
now, we can sue formula
![cos(2\theta)=cos^2(\theta)-sin^2(\theta)](https://tex.z-dn.net/?f=cos%282%5Ctheta%29%3Dcos%5E2%28%5Ctheta%29-sin%5E2%28%5Ctheta%29)
now, we can plug values
![cos(2\theta)=(-\frac{3}{5})^2-(-\frac{4}{5})^2](https://tex.z-dn.net/?f=cos%282%5Ctheta%29%3D%28-%5Cfrac%7B3%7D%7B5%7D%29%5E2-%28-%5Cfrac%7B4%7D%7B5%7D%29%5E2)
we can simplify it
![cos(2\theta)=-\frac{7}{25}](https://tex.z-dn.net/?f=cos%282%5Ctheta%29%3D-%5Cfrac%7B7%7D%7B25%7D)
