Question

Given that ∠Ф = 180°, determine the numerical value of this function.

sinФ=___.

1. -1

2. 1

3.0

Answer 1

The answer to your question is 3. 0

Explanation:

For an angle of 180°:

- hypotenuse = 1

- Adjacent side = 1

- Opposite side = 0

Then, sin Ф =
`(Opposite side)/(Hypotenuse)`

sin 180° =
`(0)/(1)`

sin 180° = 0
