82
The sum of the three angles is 180. One is given and the other we can figure out because it forms a straight line (180) with the angle to the left outside. The outside angle is 117, so 180-117 is 63.
So then add up the 3 angles in the triangle
63+35+y=180
y= 82
Answer: 4x² + 12x + 9
Explanation:
Area = (2x + 3) (2x + 3) = 4x² + 6x + 6x + 9 = 4x² + 12x + 9

The whiteboards she bought cost $35, and she spent a total of $51.20, subtract to find out the total amount she spent on posters:

So she spent a total of $16.20 on posters, now divide by the amount one poster costs to find out how many posters she bought.

So she bought 3 posters.
From my understanding your asking what 20% of $48 is.
in that case it would be $9.60
