We have that
if cos(∅)=x----------------> arccos (x)=∅
then
cos(∅)=0.63
∅=arccos(0.63)-------------> ∅=50.95°
<span>
The question does not specify in which quadrant the angle is, </span>since the cosine function is positive, the angle must be in the first quadrant or in the fourth quadrant
<span>if it is in the first quadrant the angle is </span>50.95°
and
if it is in the fourth quadrant the angle is (360°-50.95°)=309.05°
Answer:
f(x)=8,000(0.08)
Step-by-step explanation:
I am not 100% sertin but 8% = 0.08 so to find the percentage you would just multiple that by the given 8,000.
Step-by-step explanation:
