Question

In the given figure , AC = 20 , CB = 15 , AD = 24 Find AB and BD .​

Answer 1

Answer:

by pythagoras theorem

${ac}^{2}$

=

${cb }^{2} + {ab}^{2}$

=

${20}^{2} = {15}^{2} + {ab }^{2} \\ {ab }^{2} = {20}^{2} - {15}^{2} \\ {ab}^{2} = 400 - 225 \\ {ab}^{2} = 175 \\ ab = \sqrt{175 } = 13.2287565553$

So,AB=13.23CM
