Add all the numbers up then divide that by 20 that’s your answer. I will not give you the answer because you also need to learn sorry :)
Answer:
A - 22
Step-by-step explanation:
This is because when you add 90 and 68 you get 158. There are 180 degrees in a triangle so you do 180-158 to get 22.
\left[x \right] = \left[ 0\right][x]=[0]
I I think you have the correct answer!
