4x+4(3)+4(2)=y
4x+20=y
X equals the amount it cost for each ticket which is unknown. Y equals the total cost. Because the amount of the food is provided, it can be calculated unlike the tickets which is just left at 4x. The work for the snacks are upwards. Its mostly substitution.

Given that tan θ= -65/72 and that angle θ terminates in quadrant II, then what is the value of cos θ?

adoni [48]

Answer:

cosθ = $-\frac{72}{97}$

Step-by-step explanation:

tanθ = -(65/72)

If it is in the 2nd quadrant, this means that y is positive but x is negative

tanθ= opposite/adjacent or (y/x)

tanθ= $\frac{65}{-72}$

We know that the adjacent value = -72 and the opposite value = 65

The hypotenuse can be get by the following

$\sqrt{(65)^2+(-72)^2} = 97$

cosθ is just adjacent/hypotenuse

Our adjacent value is -72

Our hypotenuse is 97, therefore

cosθ = $-\frac{72}{97}$
