It would be a 7% chance that both of those would happen, I hope this helped ^^
Answer:
The answer to your question is x = 66.42° and x = 293.6°
Step-by-step explanation:
Data
cos x = 2/5
x = ?
Process
1.- Look at the sign of 2/5.
2/5 is positive so the angle we are looking for is in the first or the fourth quadrant.
2.- Remember the side that the trigonometric function relates
cos x = Adjacent side / hypotenuse
then, adjacent side = 2
hypotenuse = 5
3.- Get cos⁻¹ x
cos⁻¹x = x = 66.42°
4.- If the angle is in the first quadrant x = 66.42°
5.- If the angle is in the fourth quadrant x = 293.6°
Answer:
or in "simple" form
Step-by-step explanation:
a(2) = a(1) * (2/3) = 20*(2/3) = 40/3
a(3) = a(2) * (2/3) = 40/3*(2/3) = 80/9
Answer:
it is either the second or fourth one
