Answer:
[tex] 2 \sqrt{21} is \: the \: ans[/tex]
Step-by-step explanation:
given;abc is a right angled triangle.
by takingr eference reference angle c
p=ab=? ,h=bc=10 ,b=ac=4.
by the Pythagoras relation we get;
[tex]p = \sqrt{h {}^{2} - b {}^{2} } [/tex]
so ,p=
[tex] \sqrt{10 {}^{2} - 4 {?}^{2} } [/tex]
==
=
[tex] = 2 \sqrt{21} [/tex]
is ans
