Answer:

b is theee answer

Step-by-step explanation:

82+55+N=180

82+55-180=N

137-180=N

43=N

if nagtataka ka saan nanggaling yung 180 ang dahilan ay triangle yan,dapat pag pinagadd mo yung 3 interior angle ng triangle dapat 180,diyan naman sa sasagutan mo given na yung 2 interior angle so hahanapin mo na lang yung value nung isang angle mo,kaya yan yung naging solution
