Answer:
A. 13
Step-by-step explanation:
Pythagorean Theorem: a^2+ b^2=c^2
a = 12
b = 5
c = ?
12^2+5^2=c^2
144 + 25 = c^2
169 = c^2
c = sqrt(169)
c = 13
3x + 3 + 3x - 1 = 3x + 8
6x + 2 = 3x + 8
3x + 2 = 8
3x = 6
x = 2
HJ= 3(2) + 8 =6 + 8 = 14
HI= 3(2) - 1 = 6 - 1 = 5
IJ = 3(2) + 3 = 6 + 3 = 9
Answer is 9 f-^1
I hope this correct :D
1- r=.5
2- x=.5
