Answer:
160°
Step-by-step explanation:
The way I am doing it may not be the correct way but it works. What I did was take 90° away from 120° to make it 30° as if there is a line. I did this so I could make a triangle. Using the triangle addition postulate, I Added 30 to 80 to get 110 than subtracted that from 180 to get 70. Lastly, i added 90° to 70° to get 160°
Hope this helped you get the answer :)
![\\ \sf{:}\implies side=\sqrt[3]{14}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%7B%3A%7D%5Cimplies%20side%3D%5Csqrt%5B3%5D%7B14%7D)
Now
Cut it into 10 parts as per question(Open side means five sides hence it will be 5×2=10)
Now divide by previous side
Option D
The graph should look like this:
Answer: Obtuse angle. Obtuse angles are any angle above 90 degrees. Acute angles are any angle below 90 degrees. 90 degree angles are right angles
The answer is -10
Step by step:
-4 / 2/5
-4/1 x 5/2
-20/2 simplifies to -10
