how to find value more than 90° in sinø....means value of sin120° or sin150°.....
drushasangwan:
Subtract it from 180 and then put value
Like it is 120 then its value will be equal to sin 60

sin120= sin(90+30)= -cos30=-√3/2
Ye wrong h qki {sin (90 - theta ) = cos theta } ye identity hoti h na ki { sin (90 + theta ) = cos theta }
yes sorry
Hmmm

Answer:
Step-by-step explanation:
As commented before...
Whatever the value is say for eg 120
Subtract it from 180
So it will come 60
So value of sin120 = value of sin 60 that is root 3 by 2 ...
Similarly
Sin 150 = 1/2 ( sin 30)
...
Please mark as brainliest too
Thanks
