Question

Find the angles and marked as x and y

Answer 1

X=105
y=50
since application of linear angles property, opposite interior angles property

Answer 2

Given-AB//EF//CD

TO FIND-X AND Y

SOLUTION---We know that AB//CD

  SO ∠BCD=∠ABC  <ALTERNATE INTERIOR ANGLE>

25°+∠Y=75°

∠ Y=50°

∠ FEC + ∠ ECD = 180°

X+25°=180°

X=155°

SOLUTION----X=155° AND Y=50°
