The problem reads: Find [itex]\sin\theta[/itex] and [itex]\cos\theta[/itex](adsbygoogle = window.adsbygoogle || []).push({});

Part a gives me the coordinates [itex]\left(-1,1\right)[/itex]

The triangle I got had the [itex]x-length[/itex] as [itex]-1[/itex], while the [itex]y-length[/itex] was [itex]1[/itex]. The hypotenuse I got was [itex]\sqrt{2}[/itex]

Since [itex]\sin[/itex] is [tex]\frac{opposite}{hypotenuse}[/tex] I got [tex]\sin\theta=\frac{1}{\sqrt{2}}[/tex]

The book says it is [tex]\sin\theta=\frac{\sqrt{2}}{2}[/tex]

What did I mess up on? Data I'm waiting for you
