Answer:
C.13
Step-by-step explanation:
D is a midpoint, which means that AD=DB= 1/2 AB = 1/2 (24) = 12
Using Pythagorean theorem we know that CD^2+DB^2=CB^2
That means that 5^2+12^2=CB^2
25+144=169
169=13^2
CB=13
a=CB=13
Y = 1/3 x - 10 . . . (1)
2x + y = 4 . . . . . . (2)
Putting (1) into (2) gives, 2x + 1/3 x - 10 = 4
7/3 x - 10 = 4
7/3 x = 4 + 10 = 14
x = (3 x 14)/7 = 6
From (1), y = 1/3(6) - 10 = 2 - 10 = -8
x = 6, y = -8
Using the distance formula, you get sqrt(36+25) which is sqrt(61) which is around 7.8
