Answer:
cos(O) = 39 / 89
Step-by-step explanation:
<u>Given:</u>
ΔOPQ, where
- ∠Q=90°
- PO = 89
- OQ = 39
- QP = 80
<u>cosine of ∠O?</u>
- cos(O) = Adjacent / Hypotenuse
Use the distance formula to find this answer √(X2-X1)² + (Y2-Y1)²
I hope it's this??? but I'm not sure
I think it is 70 but not sure
We have to find the percentage ratio of two numbers. It is

. And the correct answer is D).
Alternatively, by setting up a ratio, we can write that If
400_____100%
36_____x
And x=9%
