Option (3)

Step-by-step explanation:

In a right triangle,

Cosine rule → $cos(\theta)=\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

Sine rule → $sin(\theta)=\frac{\text{Opposite side}}{\text{Hypotenuse}}$

In the given triangle,

By cosine rule,

$cos(h)=\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$cos(h)=\frac{z}{x}$

Or cos(h°) = z ÷ x

Therefore, Option (3) will be the answer.
