Question

What is the answer to this question?

Answer 1

Explanation:

I don't see the answer options.

but in line 3 this is simply done by multiplying to eliminate the fractions on the right side of the equations.

and so, since h = h, we get c×sin(B) = b×sin(C).

in the last line we divide both sides first by b and then by c and get

sin(B)/b = sin(C)/c

the law of sine ...
