Question

ABC is a parallelogram in which angle A = 68 degree.Find angle B, angle C and angle D​

Answer 1

${\huge{\underline{\sf {\blue{Answer}}}}}$

$\angle B$ = 112°

$\angle C$ = 68°

$\angle D$ = 112°

$\: \:$

${\huge{\underline{\sf {\orange{Explanation :}}}}}$

$\: \:$

We know that sum of co-interor angles are 180°

$\: \:$

$\angle A$ + $\angle B$ = 180°

68° + $\angle B$ = 180°

$\angle B$ = 180° - 68°

$\angle B$ = 112°

$\: \: \:$

Again,

$\angle B$ + $\angle C$ = 180°

112° + $\angle C$ = 180°

$\angle C$ = 180° - 112°

$\angle C$ = 68°

$\: \: \:$

Now,

$\angle C$ + $\angle D$ = 180°

68° + $\angle D$ = 180"

$\angle D$ = 180°- 68°

$\angle D$ = 112°
