Question

question 2, 4.2.3 part 1 of 6 find the six trigonometric function values of the specified angle. sinθ = (type an integer or a simplified fraction.)

Explanation:

Step1: Recall sine - function definition

In a right - triangle, $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$.

Step2: Identify opposite and hypotenuse

For angle $\theta$, the side opposite to $\theta$ has length 12 and the hypotenuse has length 13.

Answer:

$\frac{12}{13}$
