Ok, you can use the tangent function to solve this problem.
Remember that in a right triangle, such as you have here, the tangent of 52 degrees (tan(52) is the ratio of the side opposite the 52-degree angle (that's the height of the building, h) divided by the side adjacent to the 52-degree angle (that's the length of the building's shadow, or 23 ft.)
So, we can write:
Now you multiply both sides by 23 to get:
You can do this in your calculator.
Round the the nearest integer:
