Web3 E is the intersection between the line through CD and AB. It means that ∠BDE = 60° → ∠BED = 90°. Let's call AB = AC = l and BD = 2p. Considering the right triangle AEC we have AE = lsin10°. Considering the right triangle BED we have that BE = p√3 and ED = p. Then BE = p√3 = AB − AE = l − lsin10° → p = l(1 − sin10°) √3 WebClick here👆to get an answer to your question ️ \"5.
