Question

(6)
In the figure, FBC and AFE are straight lines. BDEF is a rhombus.
(a) Find Angle FBE.
(b) Find Angle ABF.

Answer 1

Answer:

(a) angle FBE=48degree

(b) angle ABF=42 degree

Step-by-step explanation:

FBC IS A STRAIGHT LINE ON AFE , THEREFORE ITS PERPENDICULAR TO EFA

now in triangle AFB ,

angle BAF+angle BFA +angle ABF=180(angle sum property of triangle)

48+90+ABF=180

138+ABF=180

ABF=180-138

ABF=42.

now BE seems perpendicular to AB .

therefore,

angle ABF+angle FBE=90

42+FBE=90

FBE=90-42

FBE=48

Answer 2

FBE = 39

ABF = 54
