Question

In A ABC right angled at A. AD is drawn such that ZDAB ZBCA, If BD = 24 cm and DC = 3 cm. find AB.

Answer 1

Answer:

Given: In the above figure [B & C are swapped in the figure],

CD=24cm, BD=3cm

m<DAC=m<CBA.

RTF: AC=?

Solution:

In the given triangle, AD²=BD*CD=24*3=72 => AD=6√2cm. AC=√(AD²+CD²)=√(72+576)=√648≈25.456cm
