Correct Answer: 56°
Solution :
AB is the diameter of the circle and ACB is a right angle because the tangent at a point on the circle is perpendicular to the radius at that point.
Given that $\angle$CAB = 34°
In $\triangle$CAB,
$\angle$CBA = 180° – $\angle$CAB – $\angle$ACB = 180° – 34° – 90° = 56°
Hence, the correct answer is 56°.
