AB is the diameter of a circle. A point C is situated on the tangent drawn on point A. If AB = 24 cm, and AC = 7 cm then find the length of BC:
Answer & explanation
Correct answer: option 3
We know that,
(Hypotnuese)2 = (perpendicular)2 + (base)2
We have,
AB = 24 cm
AC = 7 cm
ΔABC is right angle triangle =
= (BC)2 = (AB)2 + (AC)2
= BC = \(\sqrt {24^2 + 7^2 }\)
= BC = \(\sqrt {625 }\) = 25 cm
