Q7 of 100 Page 17

ABC is a triangle with B as right angle, AC=5 cm and AB = 4 cm. A circle is drawn with A as centre and AC as radius. The length of the chord of this circle passing through C and B is

Given: AC = radius = 5 cm

AB = 4 cm


DC is a chord passing B and C


In ABC


AC2 = AB2 + BC2


BC2 = 9


BC = 3 cm


CD = 2 BC


= 6 cm
