The distance between the centres of the two circles is 73 cm, and the radii of the circles are 29 cm and 19 cm. Find the length of the transverse common tangent drawn to the two circles.
Show answer & explanation
Correct answer: B
Explanation
Length of the transverse common tangent = √(73² − (29 + 19)²)
= √(5329 − 2304)
= √3025
= 55 cm
