Answer:


(48)/(13)\approx 3.7

Explanation:

Two triangles are similar by AAA ( Angles B and B' are right angles, the two angles in C are congruent because opposite by the vertex, and the third by difference). Corresponding sides are in proportion. In particular
x:6=8:13 \leftrightarrow 13x=6\cdot8 \rightarrow x = (48)/(13) \approx 3.7
