Question

Two circles touch each other externally at C. AB and CD are two common tangents. If D
lies on AB such that CD = 6 cm, then find AB​

Answer 1

Step-by-step explanation:

ANSWER

ANSWERFrom the given figure, CD = 4 cm

ANSWERFrom the given figure, CD = 4 cmCD = AD = 4CD=AD=4 (tangents drawn from an exterior point are equal)

ANSWERFrom the given figure, CD = 4 cmCD = AD = 4CD=AD=4 (tangents drawn from an exterior point are equal)CD = BD = 4CD=BD=4 (tangents drawn from an exterior point are equal)

ANSWERFrom the given figure, CD = 4 cmCD = AD = 4CD=AD=4 (tangents drawn from an exterior point are equal)CD = BD = 4CD=BD=4 (tangents drawn from an exterior point are equal)Now, AB = AD + BD = 4 + 4 = 8AB=AD+BD=4+4=8 cm
