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

Answer»

Answer:

It should be sin²θ

Step-by-step explanation:

SIN θ×sin(180-θ)=sinθ×sinθ

[As sin (180-θ) lies in second QUADRANT

In second quadrant sin is ALWAYS positive]

So,

sinθ sin(180-θ)=sinθ×sinθ=sin²θ
