Answer:

perpendicular = 10.24 cm

Step-by-step explanation:

by pythagorus theorem,

$h {}^{2} = b {}^{2} + h {}^{2}$

( where, h = hypotenuse, b = base,

p = perpendicular )

so,

=》

$13 {}^{2} = 8 {}^{2} + p {}^{2}$

=》

$169 = 64 + p {}^{2}$

=》

$169 - 64 = p {}^{2}$

=》

$p = \sqrt{105}$

perpendicular = 10.24 ( root 105 )
