Question

please tell fast and full answer with the solution​

Answer 1

Step-by-step explanation:

y+z=180(straight line)

b=180-55=125degree

Answer 2

Answer:

since 4x // to zw

so a=55° (corresponding angles)

in triangle 4xz

a+b+72=180(sum of angles of a triangle is 180)

55+72+b=180

b=180-127

b=53°

c+b+55=180(linear pair or straight line)

c+53+55=180

c=180-108

c=72°

so a=55°,b=53°,c=72° ans
