if u give me a answer by step explanation .I will surely follow u it's for math.plz​

Answer 1

Answer:

In △KPN and △KLM, we have

   ∠KNP=∠KML=46  

∘

             [Given]

    ∠K=∠K                           [Common]

∴  △KNP∼△KML        [By AA-criterion of similarity]

⇒  

KM

KN

​  

=  

ML

NP

​  

        [∵ Corresponding sides of similar triangles are proportional]  

⇒    

b+c

c

​  

=  

a

x

​  

 

⇒x=  

b+c

ac
