Answer:
It's 4
Step-by-step explanation:
* / = square root
You simply 2/72 which is 12/2, then simplify /8 which is 2/2.
You combine 2/2 and /2 which is 3/2.
The equation should be 12/2 over 3/2 so you simplify it which will give you 4.
(By simplifying 12/2 over 3/2, you cross out /2 and convert 12 over 3 into a whole number)
they are opposite
because it wont make scenes when its already 180
i Think all are correct not sure tho
