Answer:
my day is also so bad :(........
Step-by-step explanation:
Use the inverse cosine function.
Moving left subtracts from the x value the number you move.
In (2,9) the x value is the number 2
You move 1 unit to the left so subtract 1 from 2:
2-1 = 1
You will be at (1,9)
6, just divide
Hope this helps!!!! :))
The answer is 50
40-10=30
30+20=50
