Explanation:
sin25cos65+cos25sin65
=sin25.sin(90-65)+cos25.cos(90-65) [sin@=cos(90-@) & cos@=sin(90-@)]
=sin25.sin25+cos25.cos25
=sin^2(25)+cos^2(25) [sin^2(@)+cos^2(@)=1 ]
=1
Hope it will help you

Answer:
sin25cos65+cos25sin65
=sin25.sin(90-65)+cos25.cos(90-65)
=sin25.sin25+cos25.cos25
=sin²(25)+cos²(25)
=1
