Answer:
Step-by-step explanation:
use SOH CAH TOA to remember tangent sin and cosine equations
Sin = opposite over hypotenuse Cosine Adjacent over Hypotenuse Tangent Opposite over Adjacent
tangent is also equal to sin/cos
tan B = opposite of B/adjacent of B = 3/5
cos B = adjacent/hypotenuse = 5/sqrt(34)
Sin A = opposite/hypotenuse = 5/sqrt(34)
tan A = opposite/adjacent = sin/cos = [ 5/sqrt(34) ]/ [ 3/sqrt(34) ] = 5/3
