ABC is an equilateral triangle and CD is the internal bisector of ∠C. If DC is produced to E such that AC = CE, then ∠CAE is equal to
A. 45°
B. 75°
C. 30°
D. 15°
Answer: Option D
Solution(By Examveda Team)
According to question,Given : ABC is an equilateral triangle CD is the angle bisector of ∠C
AC = CE
∴ ∠CAE = ∠CEA
∠ACD = 30°
∴ ∠ECA = 180° - 30°
∠ECA = 150°
In ΔCAE
∠CAE + ∠CEA + ∠ECA = 180°
∴ 2∠CAE = 180° - 150°
2∠CAE = 30°
∠CAE = 15°
