Question

find x, jk, and jm.

Explanation:

Step1: Recognize the property

Since \( LK \perp JK \) and \( LM \perp JM \), and \( JL \) is the angle bisector, by the Angle Bisector Theorem, the distances from a point on the angle bisector to the sides of the angle are equal. So \( JK = JM \).

Step2: Set up the equation

Given \( JK = x + 5 \) and \( JM = 2x - 7 \), we set them equal:
\( x + 5 = 2x - 7 \)

Step3: Solve for x

Subtract \( x \) from both sides:
\( 5 = x - 7 \)
Add 7 to both sides:
\( x = 5 + 7 = 12 \)

Step4: Find JK and JM

Substitute \( x = 12 \) into \( JK \):
\( JK = 12 + 5 = 17 \)
Substitute \( x = 12 \) into \( JM \):
\( JM = 2(12) - 7 = 24 - 7 = 17 \)

Answer:

\( x = 12 \), \( JK = 17 \), \( JM = 17 \)
