Answer:

Step-by-step explanation:
Given:
Angle is in standard position which means the starting ray is at the origin. The terminal side has coordinates (3, -4).
So, the 'x' value is 3 and 'y' value id -4.
Using Pythagoras Theorem, we find the hypotenuse.
Hypotenuse = 
Now, using the sine ratio for the angle, we have

Therefore, the value of
is
.
The value is negative as the point (3, -4) lies in the fourth quadrant and sine ratio is negative in the fourth quadrant,
The answer is z = y over cos 50 degrees
If he chews 4 pieces of gum a day that is 28 a week so if you need 28 and gum comes in packs of 7 28/7 is 4 so he will need 4 boxes of gum a week or 18 packs a month or 213 a year
