Math Problem Statement

Find the length of the unknown segments in the given figure involving two circles and intersecting line segments.

Solution

This image contains a problem about finding the length of unknown segments in the given figures, involving two circles and intersecting line segments. Let us solve each part.


Part 1 (Left Circle - Blue):

Here, we apply the Power of a Point Theorem: Power of a Point: (XY)(XN)=(XK)2\text{Power of a Point: } (XY) \cdot (XN) = (XK)^2 Given:

  • XY=X=6XY = X = 6
  • XN=2XN = 2
  • XK2=5XK^2 = 5

Solving ... Power of Point computation for the left circle

Given values

XY = 6 # length of XY XN = 2 # length of XN area = Total valuesApologies for the confusion! I will correct and rephrase. Let’s manually compute the problem.


Solution for Left Circle:

Using the Power of a Point Theorem: XYXN=XK2XY \cdot XN = XK^2 Substitute the given values: 62=XK26 \cdot 2 = XK^2 12=XK212 = XK^2 XK=12=23XK = \sqrt{12} = 2\sqrt{3}


Solution for Right Circle:

Here, the segments are related by: (SC)(SB)=(SU)2(SC) \cdot (SB) = (SU)^2 Substitute the given values:

  • SC=4xSC = 4x
  • SB=15SB = 15
  • SU=xSU = x

The equation becomes: (4x)(15)=(x)2(4x) \cdot (15) = (x)^2 60x=x260x = x^2 Simplify: x260x=0x^2 - 60x = 0 x(x60)=0x(x - 60) = 0 So: x=0orx=60x = 0 \quad \text{or} \quad x = 60 Since x>0x > 0, we take: x=60x = 60


Final Results:

  1. XK=23XK = 2\sqrt{3}
  2. x=60x = 60
