Answer:
∠ABC = 130°
Step-by-step explanation:
In a rhombus abcd measure of angle cab is 25 then measure of angle abc
∠CAB = 25°
in Δ ABC
AB = BC ( all sides of a rhombus are equal)
AC is Diagonal
as AB = BC
=> ∠CAB = ∠ACB
=> ∠ACB = 25°
in Δ ABC
∠CAB + ∠ABC + ∠ACB = 180°
=> 25° + ∠ABC + 25 = 180°
=> ∠ABC = 130°
