Answer:

Option D.75°

Step-by-step explanation:

we know that

The sum of the interior angles of a regular dodecagon is equal to

S=(n-2)*180

where

n is the number of sides

In this problem

n=12 sides

substitute

S=(12-2)*180

S=1,800\°

Find the measure of each interior angle

Divide the sum of the interior angles by the number of sides

1,800\°/12=150\°

The measure of the angle formed by the radius and the side of a regular dodecagon is half the measure of the interior angle

therefore

150\°/2=75\°

Answer:

first one is 82% second is 214%

Step-by-step explanation:

Step 1: Divide 288 by 351 to get the number as a decimal. 288 / 351 = 0.82

Step 2: Multiply 0.82 by 100. 0.82 times 100 = 82

Step 1: Divide 212 by 99 to get the number as a decimal. 212 / 99 = 2.14

Step 2: Multiply 2.14 by 100. 2.14 times 100 = 214
