A) (-5,√29)

B) (-3,√29)

C) (-10,6)

D) (-6,10)

I drew the triangle, and aren't the coordinates supposed to be (-5,-3)? However the answer is C, I dont get it, can someone please explain?

**Reiny**, Wednesday, November 14, 2012 at 10:09amtanØ = y/x

since tanØ = -3/5 and you are in II

then y = 3, and x = -5 , or in that ratio

now look at C) with point (-10,6)

isn't tanØ = 6/-10 = -3/5 ??

It said "possible point", other points could have been

(-20,12), (-200, 120) etc

(in your diagram, the end point in II should have been (-5,3) , not (-5,-3) )
