If ∠cef is complementary to ∠dcf then
WebIf ∠CEF is complementary to ∠DCF, then∠DCF ≅ ∠FEG. Complements of the same angle are congruent. FBC and CBG are supplements, DBG and DBF are supplements, and … WebSo, ∠ACD = ∠DCF = 60° CE = External angle bisector of ∠DCF So, ∠DCE = ∠ECF = 30° ∠BCE = ∠BCA + ∠ACD + ∠DCE ⇒ 60° + 60° + 30° ⇒ 150° In ΔBCE, ∠EBC + ∠BCE + ∠CEB = 180° ⇒ 15° + 150° + ∠CEB = 180° ⇒ 165° + ∠CEB = 180° ⇒ ∠CEB = 180° – 165° ⇒ ∠CEB = 15° ∴ Value of ∠CEB is 15° Tips and Tricks: ∠CEB = ∠BAC/4 ⇒ 60°/4 = 15° …
