Answer 2

Answer:

-1.964

Step by Step Explanation

sin 35 = -0.428

cos 55 = 0.022

cos 35 = -0.903

sin 55 = -0.999

tan 15 = -0.855

tan 45 = 1.619

tan 75 = -0.42

Add

sin 35 + cos 55

= (-0.428) + 0.022

= (-0.406)---------------------------( 1 )

cos 35 + sin 55

=(-0.903)+(-0.999)

=(-1.902)----------------------------( 2 )

tan 15 + tan 45

= (-0.855)+ 1.619

=(0.764)---------------------------( 3 )

tan 75 = (-0.42)-----------------( 4 )

ADD ( 1 ),( 2 ),( 3 ),( 4 )

=(-0.406) + (-1.902) + 0.764 + -0.42

=(-1.964)

THE FINAL ANSWER IS -1.964
