Answer:
26
Step-by-step explanation:
Let 10 be a, and 24 be b, and the undefined hypotenuse be c.
[tex]a^2 + b^2 = c^2[/tex]
[tex]10^2 + 24^2 = c^2[/tex]
100 + 576 = c
c = 676
[tex]\sqrt{100} + \sqrt{576} = \sqrt{676}[/tex]
[tex]10^2 + 24^2 = 26^2[/tex]
c = 26
The value of the undefined line is 26.
