Question

in a parallelogram ABCD,If angle DAB=75° and angle ABC=105°.find angle BCD and angle ADC​?Answer is BCD=45° and ADC=105°​

Answer 1

The value of $\angle BCD\ and\ \angle ADC$ is $75 \ degree\ and\ 105\ degree$

Step-by-step explanation:

Given,

Parallelogram $ABCD$, where $\angle DAB=75\ degree\ and\ \angle ABC=105\ degree$

Find $\angle BCD=?\ and\ \angle ADC=?$

We know, In any Parallelogram,

Opposite angles are congruent.

Here in the figure,

$\angle DAB=\angle BCD$ and $\angle ABC=\angle ADC$

∴ $\angle BCD=75\ degree$  (∵$\angle DAB=\angle BCD$ and $\angle DAB=75\ degree$)

And $\angle ADC=105\ degree$ (∵$\angle ABC=\angle ADC$ and $\angle ABC=105\ degree$)

So, The value of $\angle BCD\ and\ \angle ADC$ is $75 \ degree\ and\ 105\ degree$
