Question

Vijaya says sinº 20° + sin 70° = 1". Do you agree with her statement ? Give reasons​

Answer 1

$\huge\star{\underline{\underline{\tt{\red{Answer}}}}}\star$

____________________________

sin(20°) +sin(70°) ≠ sin(90°)

So That Means

sin(20°)+sin(70°)≠1

because In Trigonometry,

Only The Angles can Be Added

The word of sin/cos /tan etc. makes it's function Change

So their individual values only can be added.

Therefore Hence proved
