The value of sin215 + sin225 + sin235 + sin245 + sin255 + sin265 + sin275 is :
Show answer & explanation
Correct answer: B
Explanation
The correct answere is option 2 i.e. 7/2.
sin215 + sin225 + sin235 + sin245 + sin255 + sin265 + sin275
Arranging the above equation we get:-
⇒ sin215 + sin275 + sin225 + sin265 + sin235 + sin255 + sin245
⇒ 6 + sin245
⇒ 6 + 1/2
⇒ 7/2
