Answer 1

D-did you use the Pythagorean Theorem to find the hypotenuse...

Answer 2

No

Answer 3

\[a^2 + b^2 = c^2 \rightarrow 9^2 + b^2 = c^2\]

Answer 4

use Pythagorean theorem to find the length of third side and at last add the lengths of all sides to get perimeter

Answer 5

\[\sqrt{9^2 + 12^2} = c^2\] Is the formula.

Answer 6

\[\sqrt{225} = c\]

Now solve that for the hypotenuse and add all parts together.

Answer 7

15.9

Answer 8

15 + 9 + 12 = 36 (you were correct)

I hope you now understand how to find the perimeter! Good luck in your future endeavors!

Answer 9
