If sin α = 0.054 and sin β = 0.655 with both angles’ terminal rays in Quadrant-I, find the values of (a) cos(a+b) (b) cos (b-a)

Question

If    sin α = 0.054 and    sin β = 0.655 with both angles’ terminal rays in Quadrant-I, find the values of (a) cos(a+b) (b) cos (b-a)

Using a table of values, you can get the values of α and β.  This tells you nothing about a and b.  May I please see the original question?
