Angles — practice question

The diagram depicts two parallel lines $PAQ$ and $SBCT$. It also gives $AB = AC$ and $ ngle QAC = 43^{\circ}$. The labelled points are $P, A, Q, C, T, S, B$. The angle at $A$ formed by $QA$ and $AC$ is marked $43^{\circ}$, while the angle at $A$ between $CA$ and $AB$ is marked $x^{\circ}$. NOT TO SCALE.
