Question

Ip:Abc triunghi dreptunghic masura lui a egal 90 grade ad perpendicular pe bc.Ab egal 36 cm si bcegal 60 cm.bd?cd?ad?ac?

Answer 1

AB=36 cm
BC=60 cm
In ∆ABC dr =>T. Cat AB²=BD×BC
36²=BD×60
BD= 1296:60
BD= 21,6 cm
BC=BD+CD=>CD = BC-BD=60-21,6=38,4 cm
In ∆ABC dr=>T. P AB²+AC²=BC²
36²+AC²=60²
AC²= 60²-36²
AC²=3600-1296
AC²=2304
AC²= √2304
AC²=48 cm
In ∆ABC dr=>T. In AD²= CD×BD
AD²= 38,4×21,6
AD² =829,44
AD²=√829,44
AD² =28,8 cm
