----
The 3rd angle must be 60 degrees also.
The triangle is equilateral.
Perimeter = 3*12 = 36

if a triangle has two angles with a measure of 60 degrees, than third angle is also 60
that triangle has also all sides same in the length
side a is equal to side b and c
if given one side with a length of 12, means each side is a length of 12

so, the perimeter of the triangle will be P=12%2B12%2B12=36
