Step 1: Make a figure from the given information Step 2: Finding the distance between the position A and tower C

Given that

Parallax angle \theta = 40\degree

Distance AB = 100 m

From the figure

\triangle ABC is a right triangle

Trigonometric ratio \tan \theta = \frac{AB}{AC}

Distance between the position A and tower C = AC

AC = \frac{AB}{\tan \theta }

AC = \frac{100}{\tan 40\degree}

AC = \frac{100}{0.8391} = 119 m

Hence,   distance between the position A and tower C, AC = 119 m
