Points A and B are on the edge of a lake. A hiker wants to know the distance from point A to point B. The hiker determines lengths of segments of triangles in such a way that two similar triangles are created and known distances can be used to determine AB. The hiker paces distances as shown in the diagram, where x = 8, y = 13, and z = 7. Determine AB to the nearest tenth. ( Drawing Attached below)

use similar triangles (proportions).

anonymous · Answer

would that be 8+13 / 8+7 = 21/20 ?

anonymous · Answer

The example that was given, made it seem that this was the first step.. It said something about AB+7/AB, but what is AB?
