Two circles touch each other at point X. A common tangent touch them at two distinct points Y and Z. If another tangent passing through X cut YZ at A and XA= 16 cm, then what is the value (in cm) of YZ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 32
AX = AY = AZ = 16 cm
YZ = 16 + 16 = 32 cm (since length of tangents from A to X and Y are same)
