1.	N a rhombus abcd, measure of angle cab is 25 , what is the measure of angle abc?
Answer» 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°

N a rhombus abcd, measure of angle cab is 25 , what is the measure of angle abc?

Answer»

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°
