Question

Find WX. Assume that segments which appear to be tangent are tangent.

Answer 1

Explanation:

Tangent from the point outside the circle are equal

WX = XY

7x - 29 = 2x + 16 {Add 29 to both sides}

7x = 2x + 16 +29

7x = 2x + 45 {Subtract 2x from both sides}

7x - 2x = 45

5x = 45 {Divide both sides by 5}

x = 45/5

x = 9

WX = 7x - 29

= 7*9 - 29

= 63 - 29

WX = 34
