While teaching at the university of pisa in 1589, galileo tested aristotle’s laws of falling objects by dropping large metal projectiles off the

Leaning Tower of Pisa

Explanation:

The Leaning Tower of Pisa is the bell tower of the cathedral in the Italian city of Pisa, which is known worldwide for its lean, and its unstable foundation. It is one of the most iconic buildings in Italy, and it is also thought to be the location of Galileo's experiments in 1589. Galileo is said to have dropped two cannonballs of different masses from the tower in order to test Aristotle's laws of falling objects.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
