If you want it in polar than George and Bill are both right. But just incase you need it in RECTANGULAR then:   Given: rSec(θ)=-5 we know that Cos(θ)=x/r since Sec(θ) =1/Cos(θ) then Sec(θ)=r/x  so plug rSec(θ)= r(r/x) that means that r2/x=-5  we know...

There are a few ways to think of the area of a triangle. I think of a rectangle. if the rectangle has height "a" and length "b" the we know that the area for that rectangle is given as "ab" or a times b. Now if we cut the triangle in half from one corner to another...
