Question

please solve this....frnd​

Answer 1

It's simple dude..

Step by step:

As u know sin30=½

But here, it's-½

So...sin must be -ve here.

As we know sin is -ve in 3rd and 4th quadrant.

So hint-1: The angle is in 3rd or 4th quadrant (ie btw 180 and 360)

So...sin (180+30)=-½

So theta =210
Also the angle is in 3rd quadrant

Hope it helped u ☺️
