Fine the measure of the angle formed by the radius and the side of a regular dodecagon.
1 answer:
Answer:
Option D.75°
Step-by-step explanation:
we know that
The sum of the interior angles of a regular dodecagon is equal to

where
n is the number of sides
In this problem
n=12 sides
substitute


Find the measure of each interior angle
Divide the sum of the interior angles by the number of sides

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

2.87 = AC
Step-by-step explanation:
Since this is a right triangle we can use trig functions
sin theta = opp / hyp
sin 35 = AC /5
5 sin 35 = AC
2.867882182= AC
To the nearest hundredth
2.87 = AC
