Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
6 = b
c= 8
a=?
now u just replace
a^2 + 6^2 = 8^2
a^2 + 32 = 64
a ^2 = 64-32
a^2 = 32
![\sqrt a^{2} = \sqrt32](https://tex.z-dn.net/?f=%5Csqrt%20a%5E%7B2%7D%20%20%3D%20%5Csqrt32)
a = 5.65685424949
if you rounded
a = 5,7
X = 352.3 [your work is correct]
then the perimeter would be 352.3 + 352.3 + 280 + 280 = 1,264.55
If you divide 8 by three and you'd get 26 but the 6 keep reapeting
Answer:
9^2= 81, √25= 5, 21^2= 441, √4= 2, √144= 12, 16^2= 256, √625= 25, (-11)^2=121
