Question

please answer fast...

Answer 1

First find out all the three sides if triangle.

OP=7cm

PQ=7-1

    =6cm

(OQ)²={(OP)²+(PQ)²}

OQ=√{49+36}

     =√85

So, sinQ=opposite/hypotonous

             =OP/OQ

     sinQ=7/√85

             =7√(85)/85

             ≈0.7592

    cosQ=Adjecent/Hypotonous

             =PQ/OQ

    cosQ=6/√85

             =6√(85)/85

             ≈0.6508

If you dont remember the formula of trig ratios, heres a small word to memorise:

SOH CAH TOA

it means

s=o/h

c=a/h

t=o/a

where s is sin, c is cos, t is tan, a is adjecent side, o is opposite side, h is hypotonous.

Hope this helps.
