The commutative property states that you can invert the order of the terms of a sum:
So, if you start with
Applying the commutative property you'll get
Answer:
cos(O) = 39 / 89
Step-by-step explanation:
Given:
ΔOPQ, where
∠Q=90°
PO = 89
OQ = 39
QP = 80
cosine of ∠O?
cos(O) = Adjacent / Hypotenuse
cos(O) = 39 / 89
71° is the answer. 44°+27°=71°
