Answer» ONG>ANSWER: ∠ABC=115 o ∠CDE=110 o ∠CBF=65 o ∴∠CFG=110 o ∴∠CFB=70 o ∠CBF+∠CFB+∠BCF=180 o 65+70+∠BCF=180 ∠BCF=180−135 ∠BCF=45

Find the angles ABC, ADE, BCD in the adjacent figure, where ‘O’ is the centre of the circle

Answer» ONG>ANSWER:

∠ABC=115

∠CDE=110

∠CBF=65

∴∠CFG=110

∴∠CFB=70

∠CBF+∠CFB+∠BCF=180

65+70+∠BCF=180

∠BCF=180−135

∠BCF=45
