3. PS= 12cm; ST=8cm; RS=12cm 4. FG= 12cm; EG= 30cm; EF= 18cm ########################### Hanya perlu ingat formula (Kalau saya guna /, ia bermaksud over, kay? Iaitu bermaksud garisan fraction tu) --tan= opposite over adjacent-- Cth: 3.a)Tan @= QS/PS b)1.5 = 18/PS c)PS = 18/1.5 d)PS = 12cm e)ST = 20-12 f)ST = 8cm g)tan @ = RS/ST h)1.5 = RS/8 i) RS = 1.5×8 j)RS = 12cm 4.a)tan x = DG/FG b)2 = 24/FG c)FG = 24/2 d)FG = 12cm e)tan y = DG/EG f)0.8 = 24/EG g)EG = 24/0.8 h)EG = 30cm i) EF = 30-12 j) EF = 8cm Kalau tak faham, memang minta maaf :( ^^
