Question

in the figure ABCD is a trapezium, FG is a straight line .Find angle EBF.​

Answer 1

Answer:

IT IS 105' BECAUSE 45' IS A INTERNALLY OPPOSITE TO ANGLE ABE. SO 180- (30+45) ANGLE ON A STRAIGHT LINE

Answer 2

Answer:

105

Step-by-step explanation:

ab parallel to dc

so ec transversal

angle bcd = angle eba = 45

then

angle eba + angle abg + angle gbc = 180 (:- because linear pairs)

45 + 30 + angle gbc = 180

75 + angle gbc = 180

angle gbc = 180-75

= 105

and

angle gbc = angle ebf (:- because vertically opposite angles)

so

angle ebf = 105
