Only answer if you know please

(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° = = ( multiply both sides by a )

a × tan38° = 6 ( divide both sides by tan38° )

a = → (b)

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
