Since it is Cos of A that means you are calculating Adjacent over Hypotenuse.
The adjacent side is 36
The hypotenuse side is 45
36/45 = 0.8

ANSWER IS 0.8

Is there any tricks to memorize the special right triangle's sides?

My algebra teacher got us all to remember that word because...
Soh - Sin = Opposite / Hypotenus
Cah - Cos = Adjacent / Hypotenus
Toa - Tan = Opposite / Adjacent
Sin, Cos, and Tan are what you can use to find missing triangle sides if you know at least one other angle besides the 90 degree angle.
