Doore Question me Angle A = 80⁰ Lena hai

[aayushkoli]

Sir second question is wrong I explain AOC-100 because triangle sum is 180, so automatically DOC-100 (V.O.A) Fully angle DOC is sum is 180 but it's sum is 200 so what is the X value
That's why this question is wrong

[rocky_editz_]

So When You Take A =80°, The Answer Will Be 30°
Explanation : When You Add B and A(B=50° andA=30°)You Will Get 130°.So to get 180°, The Other Angle Should Be 50°.So If this angle is 50°, Then the opposite should also be 50°.So in the next triangle, C is 100° and The Other Angle is 50° so by adding 100 and 50, we get 150 .So to get 180°, x should be 30° .So The Answer Is 30°
Hope This Helps😊❤

2nd question 180whole angle 50+30=80 then 180-80=100, 100ans vertically opposite 100 100+100=200 180 ke liye -20 x find -20 question he glt hai

[Ritikasinha]

30+50=80
180-80=100
100 vertically opposite angle.
100+100=200
200-180=20
Answer 100 and 20 .

Next question Mei agar 50 +30 =80 so 180-80=100 so vertically opposite will be 100 then 100 +100 =200 ???

30 hai sir answer bahot easy trick sir thanks 👍🙏

[pritibaranwal]

Sir according to first que the second que is wrong and second method we take alternate angle

[shailsutaparmar]

second me x ki value 30 hogi jaisa ki sir ne kaha hai A ko 80. lena h so answer is 30👍

[unknownsb]

In 2nd question the value of x is 30 degree

[Mr.Player]

20 ° hoga question2 ka ?? I'm right

[aaravjain]
