Question

abc is a isosceles triangle whosa equal sides ab and ac are 10cm base bc is 8cm ifc ad is perpendicular bc and aglepbc is 90 degree find area of saded postion

Answer 1

$h { }^{2} - b {}^{2} = a {}^{2}$
$10 { }^{2} - 8 {}^{2} = a {}^{2}$
$100 - 64 = {a}^{2}$
$36 = {a}^{2}$
$\sqrt{36 } = {a}^{2}$
$a = 6$
