Transcribed Image Text:**Problem 13:** If \( JH = 21 \, \text{in} \), find the length of \( KJG \).
**Diagram Explanation:**
A circle is divided into segments from the center point \( L \). The circle is segmented into the following pieces:
- Arc \( KG \) with central angle of \( 59^\circ \).
- Arc \( JI \) with central angle of \( 85^\circ \).
Other points on the circle are labeled \( K, G, H, J, \) and \( I \).
To solve for the length of \( KJG \), note:
1. \( KJG \) refers to the arc starting at \( K \), passing through \( J \), and ending at \( G \).
2. You need to determine the total angle \( \angle KLG \) by considering complementary angles that sum up to \( 360^\circ \).
Using this information, calculate the arc length using the appropriate formulas or relationships from geometry involving the proportion of \( 360^\circ \).
