Does the question let you use a calculator? If so, you simply just enter each question on the calculator (by pressing the appropriate button (i.e sin, cos, tan) that is relevant) and right down the answers provided.

 

These would be the results:

sin(20) = 0.912945250728

cos(80) = -0.110387243839

tan(35) = 0.473814720414

sin(51) = 0.670229175843

cos(17) = -0.275163338052

 

I hope this helps.
