Answer:
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.

Answer:
The top one I'm pretty sure.
One way is to graph it and do the vertical line test
it is not a function if we can draw a vertical line in the graph that passes through 2 points of the graph
if we graph this function, we see there is no place we can draw a vertical line and hit the line twice
