Question

$if \: \sin( \alpha )= \frac{4}{5} cos( \beta ) = \frac{12}{13} \: find \: \sin( \alpha ) \times \cos( \beta ) + \cos( \alpha ) \times \sin( \beta )$
​

Answer 1

Answer:

180/169 + 3√56 i/65

Step-by-step explanation:

is little different but I am thinking that if sin alpha = 4/5 cos beta = 12/13 then only my answer would be correct....
