Question

Find the value of
sin 34
COS 56°
+
cos 43°
sin 47°​

Answer 1

Step-by-step explanation:

sin 34°/cos 56°:-

34° +56° =90° means 34° and 56° are complimentary angles.

cos©=(90-©)

cos 56°=sin(90-56)°

cos 56°=sin 34°

sin34°/cos56°=sin34°/sin34°

=1

cos 43°/sin47°:-

43°+47°=90° means 43°and 47° are complimentary angles.

sin ©=cos (90-©)

sin47°=cos (90-47)°

sin47°=cos43°

cos43°/sin47°=cos43°/cos43°

= 1
