Question

in a rhombus ABCD angle A is equals Angle B minus 30 then find angle C​

Answer 1

Parallel lines property that interior angles sum is 180 degrees...

there are many ways to solve this problem...

Answer 2

let, angleA=x

angleB=x-30

In rhombus adjacent angle are supplementary then

x+x-30=180

2x=210

x=105degree

angleA= angle C .: in rhombus

angle C = 105degree
