The measure of one of its angles is 150°. The correct option is D.
<h3>How to calculate the angle?</h3>
The value of angles in a polygon is calculated by using the formula:
= (n - 2) × 180°
where n *+ number of sides
This will be illustrated as:
= (n - 2) × 180°
= (12 - 2) × 180°
= 10 × 180°
= 1800°
Since it has 12 sides, the value of each angle will be:
= Total angle / Total sides
= 1800° / 12
= 150°
The angle is 150°.

Answer:
n = 10
10, 42, 34
Step-by-step explanation:
permiter = length of each of the sides
86 = n + (4n +2) + (2n + 14)
solve for n
n = 10
put n back in the original equations
n = 10
4(10) + 2 = 42
2(10) +14 = 34

Answer:
D
Step-by-step explanation:
When something depreciates completely, it will have a total value of 0 dollars. Therefore, set the equation to zero and solve for <em>t</em> to find the years.
Therefore, the table saw will completely depreciate after 9 years.
