How can you work this out without a calculator?

Hi.
Cos A = Adjacent / Hypotenuse.
Cos A = 4 / 5
4 / 5 = 0.8
I think 4 / 8 is not very difficult to calculate without calculator. :)

Sohcahtoa...(Soh) (cah) (toa)
CosA=adj/hyp, (c=4/5),cah= .8
SinA=opp/hyp, (S=3/5),Soh= .6
TanA=opp/adj, (t=3/4),toa= .75
