Answer:
The height of the Meralco post is 251.4 meters.
```
sin(36°) = h / 500 m
h = 500 m * sin(36°)
h = 251.4 m
```
where:
* h is the height of the Meralco post
* 500 m is the distance from the observer to the base of the Meralco post
* 36° is the angle of elevation from the observer to the top of the Meralco post
The answer is rounded to the nearest meter.
