Question

Find the lettered angles in each case

Answer 1

Answer:

40°

Step-by-step explanation:

here, angle BCE = 100°

so angle FEA = 180- angle BCE = 180-100 = 80°

so according to angle sum property angle EAF = 180-(80+50) = 180-130 = 50°

so angle DFB = Angle EFA = 50°

angle DBF = 180-90° = 90° (linear pair)

so, angle x = 180-(50+90) = 180-140 = 40°

so, angle x = 180-(50+90) = 180-140 = 40° (angle sum property)
