उत्तर
If perimeter of given triangle is 38 cm, then length AP is equal to 5 cm.
Explanation:
Tangents drawn from an external point to a circle are equal.
AP = AQ
BP = BR
CR = CQ
Given the perimeter of a triangle = 38 cm
AB + BC + AC = 38 cm
(AP + PB) + (BR + RC) + (AQ + QC) = 38 cm
AP + 6 cm + 6 cm + 8 cm + AQ + 8 cm = 38 cm
28 cm + 2AP = 38 cm
2AP = 38 cm − 28 cm
AP = `10/2` cm
= 5 cm
∴ AP = 5 cm
