Question

Using the side lengths of △PQR and △STU, which angle has a sine ratio of ? ∠P ∠Q ∠T ∠U

Answer 1

Here the Sine rule is used

That is,

One side and opp angle+ one more side and angle given

Eg: side p,q and angle q

Hence,

SinP/p= SinQ /q

It is an easy method.

All you have to do is follow the Sine rule properly in order to get the answer.
