When given a trigonometric ratio, and asked to find another ratio, we draw a right triangle as shown in the picture.
From the pythagorean theorem we find the length of AB:
the numerical value of
cos∅=adjacent side/hypotenuse=
since sec∅=1/cos∅, and sec∅ is negative, then cos∅ is also negative.
Answer:
cos∅=

Option B - and
Step-by-step explanation:
Given : The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride, x. The Splash water park charges an entry fee of $60 and an additional $3 per ride, x.
To find : Which system of equations could be used to determine the solution where the cost per ride of the two amusement parks, y, is the same?
Solution :
Let x be the number of rides and
y be the cost per ride.
According to question,
The Thrill amusement park charges an entry fee of $40 and an additional $5 per ride.
The equation form is
The Splash water park charges an entry fee of $60 and an additional $3 per ride.
The equation form is
Therefore, The required system of equations form are
and
So,Option B is correct.
