First, let's sketch the problem:
To find the horizontal distance d, we can use the cosine relation of the angle 74.5°.
The cosine is equal to the length of the adjacent leg to the angle over the length of the hypotenuse.
So we have:
[tex]\begin{gathered} \cos74.5°=\frac{d}{7.9}\\ \\ 0.2672=\frac{d}{7.9}\\ \\ d=0.2672\cdot7.9\\ \\ d=2.11\text{ m} \end{gathered}[/tex]
