What evidence did galileo use to support copernicus’s model and disprove aristotle and ptolemy? check all that apply. jupiter has moons orbiting it. the sun moves from east to west. planets appear to move backward. venus has phases similar to the moon’s. the religious and cultural beliefs supported this model.

1.       Jupiter has moons orbiting it.

In addition, Galileo saw the planet's moons were moving with it.

2.       The Sun moves from east to west.

Galileo observed that the Sun has spots. The changing number(/appearance) of sunspots visible from Earth concludes that the Sun rotates on its own axis.

3.       Planets appear to move backward.

He observed that planets were moving in retrograde direction, appearing to move westward.

Explanation:

Jupiter has moons orbiting it.

The Sun moves from east to west.

Planets appear to move backward.

Venus has phases similar to the moon's.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
