The leaning tower of pisa currently "leans" at a 4 degree angle and has a vertical height of 55.86 meters. how tall was the leaning tower when it was originally built?

56 meters.

Step-by-step explanation:

Please find the attachment.

Let the leaning tower's be h meters tall, when it was originally built.

We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.

Since we know that cosine relates the adjacent and hypotenuse of a right triangle.

Upon substituting our given values we will get,

Therefore, the leaning tower was approximately 56 meters, when it was originally built.
