freind help me in question!! ​

Answer 1

$\huge\sf\pink{Answer}$

• ☞ ∠B and ∠D = 110°

• ☞ ∠A and ∠C = 70°

$\rule{110}1$

$\huge\sf\blue{Given}$

• ✭ One angle of a Parallelogram is 70°

$\rule{110}1$

$\huge\sf\gray{To \:Find}$

• ☆ All the other angles?

$\rule{110}1$

$\huge\sf\purple{Steps}$

So now ,

• ➝ $\sf \angle A = \angle C \qquad \bigg\lgroup Opposite\; Angles\bigg\rgroup$

➝ $\sf\color{aqua}{C = 70\degree}$

• ➳ $\sf\angle A + \angle B = 180\degree \qquad \bigg \lgroup Corresponding \ Angles\bigg\rgroup$

• ➳ $\sf 70\degree + \angle B = 180\degree$

• ➳ $\sf \color{lime}{ \angle B = 110\degree}$

• ➢ $\sf \angle B = \angle D \\bigg\lgroup Opposite\: Angles \bigg\rgroup$

• ➢ $\sf\color{red}{\angle D = 110\degree }$

$\rule{170}3$

Answer 2

Answer:

let ABCD is parallelogram

and take C 70

Step-by-step explanation:

angle C =angle B ( parallel ogram property)

so, angle B is 70

let angle A and Angle D take

x+x = 180

2x = 180

x= 90

angle A = angle D

90°=90°

angle A= 90°

angle B = 70

angle C= 70

angle D = 90
