Which of the following fossils or mountain evidence is found on Africa? European flora
Cynognathus reptile
Lystrosaurus reptile
Glossopteris plant
Mesosaurus reptile
Alpine Mountains

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
