A circle touches the side PQ of a ΔAPQ at the point R and sides AP and AQ produced at the points B and C, respectively. If the perimeter of ΔAPQ = 30 cm, then the length of AB is:
A. 20 cm
B. 10 cm
C. 12 cm
D. 15 cm
Answer: Option D
Solution (By Examveda Team)
AB & AC ⇒ tangent
AB = AC
ΔAPQ
x + x + a + a = 30
x + a = 15
AB = x + a = 15
