#1: By according to the Chord-Chord Power Theorem, the given suggests that:
- [tex] (ON)(NA) = (RN)(NM) [/tex]
» Substitute the given and then find x.
- [tex] (8)(x) = (12)(7) [/tex]
- [tex] \frac{\,8x\,}{8} = \frac{\,84\,}{8} \\ [/tex]
[tex] \therefore [/tex] The length of segment x is 10.5 units
[tex] \: [/tex]
#2: By according to the Tangent-Secant Power Theorem, the given suggests that:
- [tex] (VE)^2 = (VL)(VO) [/tex]
» Substitute the given and then find x.
- [tex] (10)^2 = (25)(x) [/tex]
- [tex] \frac{\,100\,}{25} = \frac{\,25x\,}{25} \\ [/tex]
[tex] \therefore [/tex] The length of segment x is 4 units
[tex] \: [/tex]
#3: By according to the Secant-Secant Power Theorem, the given suggests that:
- [tex] (IS)(IH) = (IT)(IF) [/tex]
- [tex] (IS)(IH) = (IF + FT)(IF) [/tex]
» Substitute the given and then find x.
- [tex] (16)(x) = (8 + 10)(8) [/tex]
- [tex] (16)(x) = (18)(8) [/tex]
- [tex] \frac{\,16x\,}{16} = \frac{\,144\,}{16} \\ [/tex]
[tex] \therefore [/tex] The length of segment x is 9 units
