Question

Solve for the length of KM. ​

Answer 1

Explanation:

➡JU×LU=MU×KU

➡10×2x=9(2x+2)

➡20x=18x+18

➡20x-18x=18

➡2x=18

➡x=18/2

➡x=9

KM=KU+UM

➡KM=9+2(9)+2

➡KM=9+18+2

➡KM=29

Answer 2

• KM = 29

Explanation:

Use Intersecting chords theorem and find x:

• JU * LU = MU * KU
• 10*2x = 9(2x + 2)
• 20x = 18x + 18
• 2x = 18
• x = 9

Find KM:

• KM = 2*9 + 2 + 9 = 29
