8x
_________
0
umm....... I think it was exactly 2 head
x = 13
Step-by-step explanation:
Split the triangle in to two. The dimensions of each will be 12 x 5 x X.
Use the pythagorean theorem.
h^2 = 144 + 25 = 169
h = sqrt 169 = 13
31 Centimeters
Since a square has 4 equal sides, each side will be the same in measurement. Therefore, we take our total (124 centimeters) and divide it into 4.
124 / 4 = 31
