Answer:
(b)
Step-by-step explanation:
Since the hypotenuse is not known then this excludes sine/ cosine ratios
Using the tangent ratio in the right triangle
tan38° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{6}{a}[/tex] ( multiply both sides by a )
a × tan38° = 6 ( divide both sides by tan38° )
a = [tex]\frac{6}{tan38}[/tex] → (b)
