The picture is unclear so I cannot really help. I'm sure I could if it was clearer though.
You multiply 12x8.3 and get the answer 100
Here's an example: If you have -9 and it asks for the absolute value of it, it means the opposite. The absolute value of -9 is positive 9.
90°+b+b =180
90°+ 2b=180
2b=180-90
2b= 90
<u>2</u><u>b</u><u>=</u><u>9</u><u>0</u>
<u>2</u> = 2
b=45°
ave tried I don't know if its correct
We need to see the table in order to answer the question...
