Question

in a figure ∆ABC,B=90°,BD ​

Answer 1

Step-by-step explanation:

p is brother of r

r is daughter of q

p×r÷q proves that p is son of q

Answer 2

$\huge\boxed{\fcolorbox{white}{pink}{Answer:-}}$

Given:

∠BDC=90°

∠ABC=90°

Let BCD =x

Using triangle sum property in △BDC, ∠DBC=90−x°

Also ∠ABD=x°

Using triangle sum property in △ADB, ∠BAD=90−x°

∠BDC=∠BDA[∠BDC=∠BDA=90°]

△BDC∼△ADB

Hence

BD÷CD=AD÷BD

Hence CD = 16 cm
