Answer:

<u>Answer</u><u>:</u><u> </u><u>(</u><u>√</u><u>3</u><u>)</u><u>/</u><u>2</u>

Step-by-step explanation:

\sin(35 \degree)  \cos(25\degree)  +  \cos(35\degree)  \sin(25\degree)  \\

from trigonometry identities:

\sin(a + b)  =  \sin(a)  \cos(b)  +  \cos(a)  \sin(b)  \\

a » 35°

b » 25°

Therefore;

=  \sin(35\degree + 25\degree)  \\  =  \sin(60\degree)  \\  \\  =  \frac{ \sqrt{3} }{2}
