<h3>
Answer: angle X = 70.5 degrees</h3>
=================================================
Work Shown:
Law of Cosines
c^2 = a^2 + b^2 - 2ab*cos(C)
22^2 = 20^2 + 18^2 - 2*20*18*cos(X)
484 = 724 - 720*cos(X)
484 + 720*cos(X) = 724
720*cos(X) = 724 - 484
720*cos(X) = 240
cos(X) = 240/720
cos(X) = 1/3
X = arccos(1/3)
X = 70.528779
X = 70.5
Make sure your calculator is in degree mode.
Answer:
10 pages per technician per day is the unit metric for the production work.
Step-by-step explanation:
Consider the provided information.
Stiviko's approved work plan included 4 technicians to create 200 web pages over 5 days.
They can create 200 web pages over 5 days.

That means in one day they can create 40 pages.
There are 4 technicians who work, therefore the unit metric for the production work is: 
Hence, 10 pages per technician per day is the unit metric for the production work.
Add numbers with common factors (the 5y and the 16y), subtract 17 from both sides
The answer is C. I hope this helps!
P² - r²
subtitute p =10 and r= -4
10² - (-4)² = 100 - 16 = 84
