When , Theta = 120 then , what will be the area of triangle ?​

Answer»

1/2×sides which form the angle ×sin theta

Now in case the sides which form the angle is equal can be represent as 1/2×a×a×sintheta (here a denotes side length)

1/2×a^2×sintheta

In case of angle forming sides are unequal can be represent as

1/2×ab×sin theta (here a and b are side length which forms the angle)

Now u will thinking that from where this formula come it is same as 1/2 × base ×HEIGHT

Now u will thinking the formula i discussed above have no height how it can be possible

Now let me explain u , u saw in formula asintheta or b sintheta is ur height and other side is ur base now from where it CAME .IT came from TRIGONOMETRY.

This is the answer XD

I hope it's helps you

Please marked me as BRAINLIEST answer
