Answer:
C. 8
Step-by-step explanation:
27-9r
explaintion:
3•9+3•-3r
27+3•-3r=
27-9r
The standard conversion toolbox:
x=rcos(θ)
y=rsin(θ)
Here r=7csc(θ)
so
x=7csc(θ)*cos(θ)=7cos(θ)/sin(θ)=7cot(<span>θ)
y=7csc(</span>θ)*sin(θ)=7sin(θ)/sin(<span>θ) = 7
therefore the rectangular coordinates are (7cot(</span><span>θ), 7)</span>
The answer is -28
hope this helps :)
