Question

(Sin 43 Cos 47+ Cos 43 Sin 47)=?

Answer 1

sin (A+B)= sin A cos B  + cos A Sin B 
Here a-43, and b= 47
so, sin( 43+47)
= sin 90 
=1. 

Answer 2

Answer:

$The \: value \: of \: \\sin43Cos47+cos43sin47\\</p><p>=1$

Step-by-step explanation:

$We \: know \: that:$

$\boxed {sinAcosB+cosAsinB\\=sin(A+B)}$

Here ,

A = 43° , B = 47°

Now,

$The \: value \: of \:\\sin43Cos47+cos43sin47\\</p><p>=sin(43+47)\\=sin90\\=1$

Therefore,

$The \: value \: of \: \\sin43Cos47+cos43sin47\\</p><p>=1$
