Hey I — ready when you are. Here is the solution to question 43 from the image you sent: 43. The figure below represents a quadrilateral piece of land ABCD divided into three triangular plots. The lengths BE and CD are 100m and 80m respectively. Angle ABE = 30°, angle ACE = 45° and angle ACD = 100°. Assumptions: Based on the diagram and typical geometry problems, we assume that AE is perpendicular to BC, meaning AEB = 90^ and AEC = 90^. a) Find to 4 significant figures: i) The length of AE. Step 1: Use trigonometry
