What is the cosine of 55 degrees?
0.5735764264 (nearest 10 decimal places).
What is cosine 0?
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).

-1<cosine<1
What is this expression as the cosine of an angle cos30cos55 plus sin30sin55?
cos(30)cos(55)+sin(30)sin(55)=cos(30-55) = cos(-25)=cos(25) Note: cos(a)=cos(-a) for any angle 'a'. cos(a)cos(b)+sin(a)sin(b)=cos(a-b) for any 'a' and 'b'.

Cosine 35 degrees sine 55 degrees plus sine 35 degrees cosine 55 degreees?
This is the Trig. Identity . Sin( A + B) = SinACosB + CosASinB. Hence Sin55Cos35 + Cos555Sin35 = Sin(55 + 35) = Sin(90) = 1 Verification If you take the various Sin & Cos values and multiply then add, they will answer to '1'. Hence./ (0.819153..)(0.819152...) +(0.573576...)(0,573586...) = 0.67100999 + 0.328989 = 0.99995... ~ 1. as required.
