It won't work. Angle B can't be 67 degree. If angle B is >60 degree, side AC cannot be the shortest side. But side AC is the shortest side at 18 cm. Triangle is invalid.

Pyree is right. Angle B cannot be the shortest angle as it is bigger than 60 degrees. however the opposite side is 18 which is shortest. Please check your question again.
