Find the indicated trig function ofθ, if θ is an angle in standard position with the terminal side defined by the given
point.
(12, 16); Find cos θ.
answer is 4 over 5 but how do i find this?
please help ^_^ <3

Solution :
Given ?
Solution: Given ? is an angle in standard position with the terminal side defined by the given point. (12, 16) find cos ?
one side AB =12 and another side BC =16
by Pythagoras we fine ACē=ABē+BCē
ACē=400
AC=20
know that cos ? =16/20 cos ? =4/5
