Question

If sin y° = s divided by 8 and tan y° = s divided by t, what is the value of cos y°? (4 points)

Answer 1

t/8

Explanation:

Use definition of tangent:

tan y = (sin y) / (cos y)

Substitute:

s/t = (s/8) / (cos y)

Solve for cos y:

cos y = (s/8) / (s/t)

cos y = (s/8) (t/s)

cos y = t/8
