Answer:
D = 340
Step-by-step explanation:
First, we input the value 9 in place of the variable N.
[tex]d = 360 - \frac{180}{n} \\ d = 360 - \frac{180}{9} [/tex]
Next, we begin to perform the order of operations to solve the equation. The Order of Operations (or PEMDAS) dictates that, from left to right, we should start from:
Parentheses
Exponents
Multiplying and Dividing
Adding and Subtracting
So first, we'll divide 180 by 9.
[tex]d = 360 - \frac{180}{9} \\ d = 360 - 20[/tex]
Finally, we'll subtract 20 from 360.
[tex]d = 360 - 20 \\ d = 340[/tex]
