Sin(180-theta) = sin(theta)How???????plz answer fast i'll mark brainliest​

Answer»

-theta) = sin(theta)

Answer:
As angle theta lies in the first quadrant, where, 90° < THEETA < 0°

& (180° - theeta) lies in the 2nd quadrant.

(theta means ray rotated anticlockwise) , ( - theta means ray is rotated clockwise)

We know that,sin theta is the ratio of perpendicular( opposite side) to the hypotenuse. & perpendiculars, in both the QUADRANTS( 1st & 2nd quadrant) are POSITIVE as these are going upwards. But in 3rd & 4th quadrant, perpendiculars become negative as these will be downwards.



Hope it helps...
