Answer:
→ 10 cm.
Step-by-step explanation:
Given :
• ∆ ABC is circumscribing a circle, the length of BC is _____ cm.
According to the given figure :
→ AB = AC
→ PB = RC
→ RC = AC - AP
→ RC = 11 - 4
→ RC = 7 cm
→ RC = CQ = 7 cm
→ CQ = 3 cm
→ BC = RC + CQ
→ BC = 11 cm + 3 cm
→ BC = 10 cm
Therefore, the length of BC is 10 cm.
