Answer:

We can use trigonometry to solve this problem. Let's call the height of the Meralco post "h". We can use the tangent function since we know the angle and the adjacent side:

tan(36°) = h / 500m

Solving for "h", we can multiply both sides by 500m:

h = 500m * tan(36°)

Using a calculator, we get:

h ≈ 323.46m

Therefore, the Meralco post is approximately 323.46 meters high.
