Question

If figure, PA and PB are tangents such that PA = 9 cm and ∠APB=60°. Find AB.चित्र में PA और PB व्रत की दो स्पर्श रेखाएँ है। यदि PA = 9 सै.मी. और ∠APB=60° तो AB पता करे। *

Answer 1

Answer:

Since all the 3 angles of ΔPAB is equal to 60°, therefore, we get that ΔPAB is an equilateral triangle. We know that all the sides of an equilateral triangle are equal to each other. Thus, the length of the chord AB of the given circle is 9 cm.
