-1-(under root)3 i(adsbygoogle = window.adsbygoogle || []).push({});

here we find that

r=2(hypotenuse)

a=-1(base)

b=-(under root)3

when i take sin theat= p/h=-(under root)3 / 2

theat from sin is -60

when i take cos theta = b/h =-1 / 2

which gives 120

now one is -60 and other is 120, which is the angel , i have to follow and what do i add it to?
