Answer:
e°=56°
f°=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°
