Answer:
Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal.
Example: 10% becomes 10/100 = 0.10.
Example: 67.5% becomes 67.5/100 = 0.675.
Step-by-step explanation:

First one:
cos(A)=AC/AB=3/4.24
cos(B)=BC/AB=3/4.24
Cos(A)/cos(B)=AC/AB / (BC/AB) = AC/AB * AB/BC = AC/BC=3/3=1
Second one:
To solve this problem, we have to ASSUME AFE is a straight line, i.e. angle EFB is 90 degrees. (this is not explicitly given).
If that's the case, AE is a transversal of parallel lines AB and DE.
And Angle A is congruent to angle E (alternate interior angles).
Therefore sin(A)=sin(E)=0.5
