Accepted Solution

A:

Basic points to remember1) perpendicular drawn from centre always bisects chord2) diameter is double of radius Now get revert back to Question18= chord length So, chord/2 = 18/2 = 926 = diameter26/2 = 13= radius Now As it forms right angled triangle Hence x= β( 13^2 - 9^2) = β169-81 = β88 = 2β22
