I am not quite sure what the question asks for,
But this is what i assume it wants:
Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A

: It looks like this in the calculator

× cos A=

(0.6489)
(

and cos cancels out)
A=

(0.6489)
A=49.54°
check:
cos 49.54=0.6489 (its right!)
Um, it is 1 gallon?
And, please, could you give me the brainliest answer? I need one more before I become a virtuoso and my friend and I are competing. :P
Ummm not to freak you out but what’s that in the background?
Answer:
No,
Step-by-step explanation:
each row can not have the same number of trees as the number 987 can not be evenly divided into 9 rows.
