Answer:
x-3=x+12
Step-by-step explanation:
because some number is x minus 3 would be x-3 is equal to so put an equal sign the product of the number x and 12

Step-by-step explanation:

The vertex angle of any triangle of the dodecagon formed by radii and a side is 360/12=30º.
The half-length of the base of the triangle is sin15=0.2588 approx.
Since there are 12 sides there are 24 half-sides in the perimeter=6.2117.
