Question

Find the value of AB in the given figure.​

Answer 1

AB = 6 cm

Explanation:

`In\:\triangle ABC,\:\angle B =90\degree...(Given)\\\\ side\: AB = side\: BC...(Given)\\\\\implies \angle BAC= \angle BCA= 45\degree\\\\\implies \triangle ABC\: is \: 45\degree-45\degree-90\degree \:\triangle\\\\\implies AB = (1)/(\sqrt 2) AC\\\\\implies AB = (1)/(\sqrt 2)* 6\sqrt 2\\\\\implies AB = 6\: cm`
