$16^2+x^2=30^2\\
x^2=900-256\\
x^2=644\\
x=\sqrt{644} \vee x=-\sqrt{644}\\
x=2\sqrt{161} \vee x=-2\sqrt{161}$

Like before, we will calculate this by using ratios and because these two triangles are similar, which is very important.

Explanation:

We see that the TK = 65 corresponds to the MV = 30. Therefore, TU = 39 corresponds to the LM = x .

65 : 30 = 39 : x

x = (30*39)/65

x = 1170/65

x = 18.

The correct answer is C. 18.
