C - is a hypotenuse,
so we can use Pythagorean theorem.
c² =a² +b²
c² = 8²+12²=64 + 144 = 16*4 +16*9=16(4+9) =16*13
c²=16*13
c=√(16*13)=√16*√13=4√13
c=4√13
Answer C. 4√13

hahahahha
The 2 triangles in the big triangle are similar so we can write
3x / 3x - 2 = 5x / 3x
9x^2 = 15x^2 - 10x
6x^2 - 10x = 0
x(6x - 10) = 0
x= 0 or 5/3
Judging by the model I would assume that ΔDBC is congruent to ΔDBA.
Thus, line CD should be congruent to line AD as well, which the solution should be line CD=13 units.
