Answer:
The answer to your question is:
a) sinФ = -4/√17
b) cosФ= 1/√17
c) tanФ = -4
Step-by-step explanation:
Just draw a right triangle where the opposite leg is -4/√17 the adjacent leg is 1/√17 and the hypotenuse is 1.
then sine Ф = opposite / hypotenuse = -4/√17 / 1 = -4/√17
cosine Ф = adjacent /hypotenuse = 1/√17 / 1 = 1/√17
tan Ф = opposite / adjacent = -4/√17 / 1/√17 = -4/1
