Question

A, E and B lie on a straight line segment.

Answer 1

The length of line BE on the given line segment is 3.5 m.

The given parameters:

• Length BD = 3 m
• Length CD = 15 m
• Length AB = 21 m

The sketch of the given line segments is presented in the diagram uploaded.

The length of BE is determined by applying similar triangle theorem as follows;

$\frac{CB}{AB} = \frac{BD}{EB} \\\\\frac{15 + 3}{21} = \frac{3}{EB} \\\\18EB = 63 \\\\EB = \frac{63}{18} \\\\EB = 3.5 \ m$

Thus, the length of line BE on the given line segment is 3.5 m.
