Question

telllllll the solutiin​

Answer 1

Answer:

Step-by-step explanation:

Note: Three letter words are angles and two letter words are sides

abc=acb (since ab=bc ) let it be y

Now 2y+x=180(angle sum property)

y=(180-x)/2------------ eqn 1

Now,

In triangle acd

acd=180-acb (straight line)

acd=180-y

Put y from eqn 1

acd=180-((180-x)/2)

acd=180-90+x/2

acd=90+x/2

Also

cad=adc=2x(ac=cd)

acd+cad+adc=180(angle sum property)

90+x/2+2x+2x=180

4x+x/2=90

9x/2=90

9x=180

x=20

Hence x=20° answer
