Answer 2

Answer:

here's the answer

Step-by-step explanation:

in triangle ANC,

it is given that,NA=NB

so,the angles formed at A and B are equal

so,we get, a=75°

now ,

75°+75°+b=180°

(angle sum property)

b=180°-150°=30°

b=30°

also a=d because(AB ||line 'N')

d=75°

also,c=B=75°

(alternate angles)
