Answer 2

Step-by-step explanation:

Given :

∆ ABC is a right angled triangle

AD = 4 units

DC = 9 units

BD is perpendicular to AC.

To find:

l(BD)

Solution:

∆ABC is a right angled triangle... (Given)

BD is perpendicular to AC ... ( Given)

BD^2=AD×DC ... ( Theorem of Geometric Mean)

BD^2=4×9

BD^2= 36

BD= 6 ... ( Taking square roots throughout)

Therefore,

length of segBD is 6 units.
