Fatima wants to find the value of sine theta, given cotangent θ = 4/7.
which identity would be best for fatima to use?

a. cosine θ = 1 / secant θ
b. sine² θ + cosine² θ = 1
c. cosecant θ = r/y
d. 1 + cotangent² θ = cosecant² θ

The answer to your question is letter D.

Step-by-step explanation:

I recommend to use the last identity to find the value of sine Ф, for two mains reasons:

1.- The data that Fatima has is the cotangent and this function is in the identity that I chose.

2.- In this identity we get the cosecant that is the inverse of the sine.

Example

               1 + (4/7)² = cosecant² Ф

                1 + 0.5714² = csc²Ф

                 1 + 0.3265 = csc²Ф

                1.3265 = csc²Ф

                 cscФ = 1.1518

                 sinФ = 1 / 1.1518

                  sinФ = 0.8682
