Question

Find x. Assume that segments that appear tangent are tangent.

Answer 1

x = 5.

Explanation:

Finding lengths of the unmarked sides:

PQ = PW = 3

QR = 2

VW = 6

ST = 9 ( because in each case lines drawn from a point outside a circle as tangents to the circle are congruent)

S0 x = PQ + QR

= 3 + 2

= 5.
