Alik [6]

Answer:

Step-by-step explanation:

a. HM = 14

HN = 21

HK = 10.5

Based on intersecting chords theorem,

HK*HJ = HM*HN

10.5*HJ = 14*21 (Substitution)

HJ = 294/10.5

HJ = 28

b. VC = 7.2

VG = 12

Based on tangent-secant theorem, thus:

VD*VC = VG²

VD*7.2 = 12²

VD = 144/7.2

VD = 20

Therefore,

CD = VD - VC

CD = 20 - 7.2

CD = 12.8
