Answer:
cos∅ =
Step-by-step explanation:
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∅=

SOLVE FOR X, Y
x=12
y=−6
Step-by-step explanation:
Input 15 as the initial value and (3, 90) as x and y to get the equation 90=m(3)+15. Isolate m to get m=25. Each shirt costs $25 and the equation that represents the scenario is y=25x+15.
