To continue a survey line AB past an obstacle, a line BC 100 m long was set out perpendicular to AB and from C angles BCD and BCE were set out at 60° and 45° respectively. Determine the lengths which must be chained off along CE in order that ED may be in AB produced?

To continue a survey line AB past an obstacle, a line BC 100 m long was set out perpendicular to AB and from C angles BCD and BCE were set out at 60° and 45° respectively. Determine the lengths which must be chained off along CE in order that ED may be in AB produced? Correct Answer 141.42 m

Angle ABC is 90°. From ∆BCE, and CE = BC sec 45° = 100 × 1.4142 = 141.42 m.
