Question

Find the value of of x and y from the given figure​

Answer 1

Answer:

If AB parallel to CD

x+angle CFE=180°(linear pair)

angle CFE=75°(corresponding angles are equal)

x+75=180

x=180-75

x=105°

and we've

x+y+30=180°(sum of all interior angles of a triangle)

105+y+30=180

135+y=180

y=180-135

y=45°

hope it helps
