To find out how high the ladder reaches up the side of the building, we can use trigonometry. Specifically, we utilize the sine function:
The height can be calculated using the formula:
In this case:
Calculating that gives approximately:
So the ladder reaches about 29 feet up the side of the building!
Using the ladder at an angle that’s too steep or too shallow could lead to difficulties. Make sure to check the angle for safety—never try to lean a ladder against a surface without ensuring it’s secure! It’s always good to refresh yourself on ladder safety guidelines to prevent accidents.
