When doing trigonometric ratios remember SOHCAHTOA
SOH = sin=opposite/hypotenuse    CAH= cos = adjacent/hypotenuse 
TOA = tan = opposite/adjacent

The answer is A) tanY = 7/4     tanZ = 4/7

Answer:

A) tan Y = 7/4; tan Z = 4/7

Step-by-step explanation:

The tangent ratio is opposite/adjacent.

The tangent of angle Y is the side opposite Y, 7, over the side adjacent Y, 4; this gives us tan Y = 7/4.

The tangent of angle Z is the side opposite Z, 4, over the side adjacent Z, 7; this gives us tan Z = 4/7.
