Answer 1

Answer:

it is a geometry try to do yourself this is not come in phone draw

Answer 2

Corrected question: In triangle ABC, ∠C = 90° AC = BC = 6 cm, find AB.

The length of AB is $6\sqrt{2} cm$

• Given,

                    ∠C = 90°

                   AC = BC = 6 cm

• ABC is right angle isosceles triangle with right angle at C and AC,BC as equal sides.

• We know that, in a right angle triangle

                   $hyp^{2}=opp^{2}+adj^{2}$

         Here,

                   $AB^{2}=AC^{2}+BC^{2}$

                   $AB^{2}=6^{2}+6^{2}$

                   $AB^{2}=36+36$

                    $AB=\sqrt{72}$

                    $AB=6\sqrt{2} cm$
