Question

HELP
35) Find the measure of line segment WV.
A) 3
B) 4
C) 5
D) 6

Answer 1

Explanation:

secants originating from the same point have the same relative length relationship :

outside part × sum of outside and inside parts

is the same for every secant from the same point.

so,

5×(7+5) = 6×(2x-8+6) = 12x - 12

60 = 12x - 12

12x = 72

x = 6

WV = 2x - 8 = 2×6 - 8 = 12 - 8 = 4

so, B is correct.
