A statue 3.6 m tall stands on a pedestal…

Step 1. The pedestal. Let it be $p$. At $45°$, $x = p$.

Step 2. The statue's top. $\tan 60° = \dfrac{p + 3.6}{x}$, so $p + 3.6 = p\sqrt{3}$.

Step 3. Solve. $p(\sqrt{3} - 1) = 3.6$, so $p = \dfrac{3.6}{0.732} \approx 4.92$ m.

Step 4. The top of the statue. $4.92 + 3.6 = 8.52$ m above the ground.
