Answer 1

Step-by-step explanation:

5)

AN=AC

ANC=ACN=64°

NCB=180-84-64=32°

NBC=64-32=32°

FROM 1 AND 2

NCB=NBC

therefore, NB=NC

I haven't mentioned reasons of 5th (cause m in hurry) you can check 6th for reasons they are the same...

6)

ABC=ACB {AB=AC}

.

FROM IT WE GET ABC=ACB=70 {ASP OF TRIANGLE}--1

.

BDC=DBA+DAB {EX.ANGLE PROPERTY}

BDC=70---2

FROM 1 AND 2

BDC=BCD {BCD=ACB}

THEREFORE BD=BC {ISOSCELES TRIANGLE CONVERSE}

Answer 2

solution of 6th

since AB= AC

<C=<B

now since

<C=<B

lineDB = CD (angles opposite to equal angles are equal)
