Question

abc in a right angled triangle right angled at b. from b , perpendicular bd is drawn on ac. if ab=8cm, bc=6cm, then bd=?​

Answer 1

ab in right angled triangle ,right angles at the b. b perpendicular bd is drawn on AC. if ab =8cm, bc=6cm,then bd=

Step-by-step explanation:

8cm

Answer 2

Answer:

√11 or √39

step explanations

In triangle ABC

AC^2=AB^2+BC^2

AC^2=8^2+6^2

AC^2=64+36

AC^2=100

AC=10

In triangle ABC BD perpendicular to AC

so AD=DC

AD=1/2AC

AD=5cm

In triangle ABD

AB^2=BD^2+AD^2

8^2=BD^2+5^2

64=BD^2+25

BD^2=64-25

BD=√39

OR

In triangle BCD

BC^2=BD^2+DC^2

6^2=BD^2+5^2

BD^2=36-25

BD=√11.
