Answer:

150

Step-by-step explanation:

To find the measure of an interior angle of a regular dodecagon we use the formula : Sum = (n-2)180

There are 12 sides in this polygon. The "n" represents the number of sides in the polygon.

Sum = (n-2)180

= (12-2)180 = 10(180) = 1800.

But this the TOTAL amount of interior angles in this polygon. We only have to find 1. Like I said, there are 12 sides in this polygon and tofimdkne side we divide by 12.

1800 ÷ 12 = 150

Answer:

150°

Step-by-step explanation:

You are given the formula for the sum of the interior angles where n is the number of sides.

Substitute 12 in:

(12-2)×180

=10×180

=1800

To find an individual angle, divide the sum by n.

1800÷12=150

Let $x,y$ be the legs of the triangle, with $x[tex]\mathrm{area}_{\rm square} = y^2$

$\mathrm{area}_{\rm triangle} = \dfrac12 xy$

The square has 3 times the area of the triangle, so

$y^2 = \dfrac32 xy$

Meanwhile, in the triangle we have

$\tan(\theta) = \dfrac xy$

Now,

$y^2 = \dfrac32 xy \implies \dfrac23 = \dfrac xy \implies \boxed{\tan(\theta) = \dfrac23}$
