Question

In the adjoining figure, ABC is right-angled at B and angle A =45°. If AC =3√2 cm, find i BC, ii AB.​

Answer 1

Step-by-step explanation:

$as \: the \: angle \: a = {45}^{0} \: angle \: b = {90}^{0} \: so \: angle \: c = {45}^{0} \\ so \: ab = bc \\ s o \: ac = 3 \sqrt{2} = ab\sqrt{2} \\ ab = 3 = bc$
