If sin θ = 15 over 17, use the pythagorean identity to find cos θ.

cos (theta) = +/- 8/17

Step-by-step explanation:

Use the definition of cosine to find the value of cos (theta)

cos (theta)=adj/hyp

Substitue in the known values

cos (theta)=+/- 8/17

8y^50

step-by-step explanation:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
