Trick question.... you only have 1 brachiocephalic trunk. It comes off the right side of the aortic arch (right side from anatomical position, or the patient's perspective) and immediately splits into the subclavian artery and the common carotid artery. On the left side of the arch the subclavian and common carotid branch directly off the aortic arch. Hopefully this makes sense.
The brachiocephalic artery divides into the right common carotid artery and the right subclavian artery.
There is an article in Wikipedia on the subject - This is a direct quote... "There is no brachiocephalic artery for the left side of the body. The left common carotid, and the left subclavian artery, come directly off the aortic arch. However, there are two brachiocephalic artery" See the related link for the full article.
In the human, the right common carotid artery branches from the brachiocephalic artery, whereas the left common carotid artery comes directly from the aortic arch. In the cat, both common carotid arteries branch from the brachiocephalic artery.

As indicated by the name, subclavian, these arteries are located beneath the clavicles. On the right, the subclavian artery arises from the brachiocephalic artery and extends to the axillary artery. The left subclavian artery arises from the aorta distal to the left carotid and extends to the axillary artery.The subclavian arteries (left and right) are branches of the aorta supplying both the left and right arms respectively.The left subclavian artery stems directly from the AortaThe right subclavian artery is a branch of the brachiocephalic artery when itbifurcates into the common carotid artery and the right subclavian artery.The subclavian veins are continuations of the axillary veins. They are joined by the internal jugular veins to form both the right and left brachiocephalic veins then drain into the superior vena cava. The nerve to subclavius or subclavian nerve is a branch of the brachial plexus which arises from the junction of the fifth and sixth cervical ventral rami.

Brachiocephalic trunk Left common carotid artery Left subclavian artery
The left brachiocephalic vein is longer than the right brachiocephalic vein. This is because the left brachiocephalic vein has to travel a greater distance across the thorax to connect to the superior vena cava, as it crosses over the midline. In contrast, the right brachiocephalic vein is shorter and more vertical, as it is positioned closer to the superior vena cava.

The three main branches at the top of the aortic arch are the brachiocephalic artery, left common carotid artery, and left subclavian artery. The brachiocephalic artery supplies blood to the right arm and the right side of the head and neck. While the left common carotid artery supplies blood to the left side of the head and neck, the left subclavian artery is responsible for blood supply to the left arm.
In the human, the right common carotid artery branches from the brachiocephalic artery, whereas the left common carotid artery comes directly from the aortic arch. In the cat, both common carotid arteries branch from the brachiocephalic artery.

The brachiocephalic trunk is a major artery that branches off from the aortic arch, supplying blood to the right arm, head, and neck. It is only present on the right side of the body because the left subclavian and left common carotid arteries branch directly off the aortic arch, eliminating the need for a separate brachiocephalic trunk on the left side.
