triangle
square
hexagon
dodecagon

Step-by-step explanation:

The 12 points marked can be divided into this many equal-size groups:

3, 4, 6, 12

so the figures that can be constructed are ...

triangle . . . . connects every 4th mark
square . . . . . connects every 3rd mark
hexagon . . . .connects every other mark
dodecagon . . connects every mark

_____

12 is also divisible by 1 and 2, but the minimum number of vertices in a regular polygon is 3.

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

Step 1: Identify Variables

Angle θ = 40°

Opposite Leg = x

Adjacent Leg = 21

Step 2: Solve for x

Substitute in variables [tangent]: $\displaystyle tan(40^\circ) = \frac{x}{21}$
[Multiplication Property of Equality] Isolate x: $\displaystyle 21tan(40^\circ) = x$
Rewrite: $\displaystyle x = 21tan(40^\circ)$
Evaluate: $\displaystyle x = 17.6211$
Round: $\displaystyle x \approx 17.6$
