2bd = angle bad

Step-by-step explanation:

i hope it will you

Answer 2

Answer:

4.5cm

Step-by-step explanation:

in triangle ACB AND triangle ADB

AC=AD          (GIVEN)

∠CAB=∠BAD(GIVEN)

AB COMMON

therefore triangle ACB AND triangle ADB are congruent

CB=BD(C.P.C.T.)

2(1.5)+1/2(1.5)= 4.5

ANS=4.5cm
