Answer:
If Sin is 11/20
What is Cos?
COS is 59/20
Step-by-step explanation:
from trigonometry basics we have SOH CAH TOA
SOH means sine = opp/hypo
CAH means cos = adj/ hypo
TOA means tan = opp/ adj
in a right angle triangle the sum of sides is equal to 90degree
if sine = 11/20 the it means the the opposite(OPP) = 11 while the Hypotenus side(Hyp) = 20
then we have to find our adjacent , 11+20+ adj= 90
31+ adj =90
adj = 90-31
adj= 59
therfore, COS = ADJ/HYP
COS= 59/20
