Which of the following can be used to calculate the height of the river dam? $\frac{115}{\cos 50^{\circ}}$ $115 \cos 50^{\circ}$ $115 \tan 50^{\circ}$ $\frac{115}{\sin 50^{\circ}}$

Step 1 ：Calculate the height using the sine function: height = distance * sin(angle)

Step 2 ：Substitute the given values: height = 115 * sin(50°)

Step 3 ：Simplify the expression: height = \(\frac{115}{\sin 50^\circ}\)

Step 4 ：\boxed{\text{Final Answer: } \frac{115}{\sin 50^\circ}}
