<p>If in a triangle ABC; ∠C = π/8; a = √2; b = √(2 + √2) then the measure of ∠A can be:</p>
Step-by-Step Solution
Key Concept: Apply the sine rule to relate sides and angles in a triangle
<p>Using the sine rule: $\frac{a}{\sin A} = \frac{b}{\sin B}$</p><p>With $\angle C = \frac{\pi}{8}$, $a = \sqrt{2}$, $b = \sqrt{2 + \sqrt{2}}$, we find $\angle A = 45°$</p>
Correct Answer: A
