Question

evaluate this EQ....​

Answer 1

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 2

Answer:

sin25cos65+cos25sin65

=sin25.sin(90-65)+cos25.cos(90-65)

=sin25.sin25+cos25.cos25

=sin²(25)+cos²(25)

=1
