Question

ABC is a right triangle with a right angle at A. find X the length of DC

Answer 1

by pythogoras theorem,AC=2√39
AD=4√6,DC=AC-AD=2.69

Answer 2

Answer:

2.69 cm

Step-by-step explanation:

$H^{2} = A^{2} + O^{2}$

AD = $\sqrt{14^{2} - 10^{2} }$

AD = 9.80 cm

AC = $\sqrt{16^2 - \\10^2}$

AC = 12.49 cm

x = 12.49 - 9.80

x = 2.69 cm
