Question

can u help me with this two answer
​

Answer 1

Answer:

yes

Step-by-step explanation:

Q1- angle AOB=DOE (VERTICALLY OPPOSITE ANGLES)

Angle BAO=DEO (alternate interior angle)

same with ABO AND DEO

Answer 2

Answer:

Step-by-step explanation:

Given 2 figures, we have to find out the value of x in each case

In figure 1,

Construct a line OE parallel to AB and CD,then

104°+∠1 = 180°    (∵angle on the same side of transversal)

⇒ ∠1 = 180°-104°=76°

116°+∠2=180°       (∵angle on the same side of transversal)

⇒ ∠2=180°-116°=64°

∠x=∠1+∠2=76°+64°=140°

In figure 2,

∠ABO=∠3=40°    (∵Alternate angles)

∠CDO=∠4=35°    (∵Alternate angles)

Total angle at center O is 360°

⇒ ∠O=∠3+∠4+x

⇒ 360°=40°+35°+x

⇒x=360°-40°-35°=285°
