C * 21.2 ° A ← CD Verified answer AD CD . | DB | D 8.45 km- Let A and B be the two towns, C the plane and CD its height, we have the following: = tan 21.2 ° = 0.38787 CD = 0.38787 AD ....... .. . [ 1 ] 12.3º . * = tan 12.3 ° = 0.21804 CD = 0.21804 DB Equating with [ 1 ] , we get B 0.38787 AD = 0.21804 DB But DB = 8.45 - AD , then 0.38787 AD = 0.21804 ( 8.45 - AD ) 0.38787 AD = 1.84243 - 0.21804 AD 0.38787 AD + 0.21804 AD = 1.84243
