Question

Triangle ABC is an isoceles triangle in which angleA is 90degree and BC=6 cm . Then AB =?

Answer 1

by Pythagorean theorom

because angle A =90

let ,the two side of the angle be x cm

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

$2 {x}^{2} = 36$

${x}^{2} = 36 \div 2$

$x = \sqrt{18}$

$x = \sqrt[3]{2}$
