Since there is no image given, the perimeter is the sum of measurement of the sides of the triangle. Assuming that the triangle is equilateral. Then the perimeter of the triangle is equal to
P = x + x + x
P = 3x
P = 30 mm
The answer would be 42 because its the same angle as the other one
I hope I helped! ♥
6.62m should be the correct answer
