Answer:
D. 1800°
Step-by-step explanation:
The given polygon has 12 sides.
The formula for finding the sum of the interior angles of an n-sided polygon is given as, ( n − 2 ) × 180.
Where n is the number of sides of the polygon.
Thus, the sum of the interior angles of the 12 sided polygon given above is:
(12 - 2) × 180
= 10 × 180 = 1800°
<em>Sum of the measures of the interior angles of the 12-sided polygon is D. 1800°</em>
First you need to turn 9.5% into a decimal so you need to move the dot " . " over to the left two times 9.5 ---> .95 ---> .095
Now that you turned the % into a decimal all thats left to do is multiply .095 by $97.95
$97.95 * .095= $9.30525 or $9.31
So the tax is $91.31
A = (B+b)·h/2 = 48 and B=b+6
2·48 = (b+6+b)·8
12 = 2b + 6
6 = 2b
b = 3 <span>inches
B = 9 </span><span>inches</span>
