Use the diagram to express each ratio as a fraction.

Answer/Step-by-step explanation:

Recall the acronym for trigonometric ratios: SOHCAHTOA

SOH means sine of the reference angle = opp/hypotenuse

CAH means cosine of the reference angle = Adj/hyp

TOA means tangent of the reference angle = opp/adj

a. Reference angle = A

opp = 15

hypotenuse = 17

Therefore:

b. Reference angle = A

Adj = 8

hypotenuse = 17

Therefore:

c. Reference angle = A

Adj = 8

Opp = 15

Therefore:

d. Reference angle = B

Opp = 8

hypotenuse = 17

Therefore:

e. Reference angle = B

Adj = 15

hypotenuse = 17

Therefore:

d. Reference angle = B

Opp = 8

Adj = 15

Therefore:
