C) $sin\theta+cos\theta$

Step-by-step explanation:

$(sin^2\theta+cos^2\theta)(sin\theta+cos\theta)$

$sin\theta+cos\theta$

Recall the Pythagorean Trigonometric Identity where $sin^2\theta+cos^2\theta=1$ , so $1(sin\theta+cos\theta)=sin\theta+cos\theta$

Step-by-step explanation:

To start this problem off, we should know an important trig rule:

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

From here, it is simple:

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

I hope this helps! Let me know if you have any questions :)

Step-by-step explanation:

Formula- base x height divided by 2

base-4

height-4

4x4=16

16/2=8

therefore, B is the correct answer
