8)
cos Z = 16/20 = 4/5
9)
tan Z = 7/24
10)
tan C = 27 / 36 = 3/4
11)
sin C = 24/30 = 4/5
I thinks it’s c but cover your name so people don’t see it
Answer:
<h2>a) 24.39</h2><h2>b) 13.78</h2><h2>c) 7.92</h2><h2>d) expanding the business.</h2><h2>h)

e), f) and g) has shown in the given image.
h) The slope is 
Here the slope means the change of number of packages with time.
Step 1: Find the circumference of the circle
Formula for circumference: C = 2 * pi * r
C = 2 * pi * 27
C = 54pi
Step 2: Find the length of the desired arc
We are only looking for 20 degrees out of 360 degrees, therefore we can multiply our circumference by 20/360.
20/360 * 54pi = 3pi units
Hope this helps!
