DE is a tangent to the circumcircle of ΔABC at the vertex A such that DE || BC. If AB = 17 cm, then the length of AC is equal to
A. 16.0 cm
B. 16.8 cm
C. 17.3 cm
D. 17 cm
Answer: Option D
Solution (By Examveda Team)
According to questionGiven:
DE || BC, AB = 17 cm, AC = ?
∠DAB = ∠ACB
(By alternate segment theorem)
∠DAB = ∠ABC
(Alternate angle)
∴ ∠ABC = ∠ACB
AB = AC = 17 cm
