Answer:

sinC = $\frac{h}{a}$

Step-by-step explanation:

Since the red line is an altitude then the triangles are right, thus

sinC = $\frac{opposite}{hypotenuse}$ = $\frac{h}{a}$

Answer:

$\Large \boxed{\mathrm{\bold{C}}}$

Step-by-step explanation:

$\sf \displaystyle sin(\theta)=\frac{opposite}{hypotenuse}$

The side opposite to $\angle C$ is h.

The hypotenuse of the smaller right triangle is a.

$\sf \displaystyle sin(C)=\frac{h}{a}$
