Find the value of cos25°−sin65°cos25°+cos65°\frac{cos25° - sin65°}{cos25° + cos65°}.

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 0.

cos25°−sin65°cos25°+cos65°\frac{cos25° - sin65°}{cos25° + cos65°}

=cos25°−cos25°cos25°+cos65°=\frac{cos25° - cos25°}{cos25° + cos65°}

=0cos25°+cos65°=\frac{0}{cos25° + cos65°}

= 0
