Answer:

e°=56°

=60°

Explanation:

(e) ∆ABC is iscosceles ,with AB=BC,

Here AB=BC

imply that angle BAC= angle BCA=62°

now,in a triangle sum of all angles are equal

so, 62°+62°+e°=180° {sum of all angles of triangle is 180°}

i.e, e°=180°-124°

i.e, e°=56°

(f) here in this triangle,all sides are equal

imply that all angles are equal

i.e, angle BAC=angle ABC=angle ACB =f°

i.e, f°+f°+f°=180°

i.e, 3f°=180°

i.e, f°=60°

Answer:

e = 56°

f = 60°

Explanation:

Angle C = Angle A = 62

e = 180 - 2(62) = 56°

Angle A = Angle B = Angle C

(Equilateral triangle)

f = 180/3 = 60°
