Let triangle ABC A=X B=90 C=180-125=55---because straight line is 180 A+B+C=180---angle sum property of triangle X+90+55=180 X+145=180 X=180-145 X=35 1like for my trick

Let ABC be a ∆ in which Angle A = X Ang. B = 90 ° . But here ang. ABm = 125 ° We know that an ext. Angle of a ∆ Is equal to the sum of two opp. Interior angles Therefore, Angle A + Ang. B = 125° = X° + 90° =125° And we got X° = 35

Let triangle ABC A=x B=90 C=180-125=55 (linear pair) A+B+C=180(Angle sum property of triangle) x+90+55=180 x=180-145 x=35
Maam but you didn't tell that the angle is 90
180 - 125 We get one interior angle And the a right angle 90 One interior angle we get that 55 so 180 - 55 + 90 = 35 Other way to solve this questions Can i hit some liken 😅😅😅

Let triangle ABC, ANGLE,B+125=180 (L.P) B=180-125=55 ANGLE,B=55 ANGLE A=55 (ALTERNATE ANGLES) SO, X+55=90 X=90-55 X=35. SO, X=35

It's perpendicular In RD
The epic line "Yeh toh zabardast hai"
180-125=55 ab x+90+55=180. 180-145=x. 35
How can you say that the angle is 90 degrees?

Because it is perpendicular on line m
Consider triangle ABC A=x B= 90° (By parallel lines) you said 😅 C= ? So ,don't worry 😊 • Angle BCM - angle ACB = angle BAC 180 - 125 ❤ You got it 55= Angle BAC • angle ACB =angle BAL ( By alternate interior angle) 55 = angle BAL Hence , Angle ABL =90° ( Parallel lines) Angle ABC - ange BAC =90° X+ 55 =90 X= 90-55 X= 35. You know The answer 💯
Yaar ye bhi to batana padta h that vo transversal m ke perpendicular haii!!
Simplest question from lines and angles
😂
No one thought about alternate interior angles😅

Use alternate interior angle easiest way

55 + 90 =145 (180 - 145 =35) 😮😮😮
Mam that's simple 😂alt.int.angle
Also be done by Angle Sum property and co interior angles and alternate interior angles,etc...
guys lemme show u a trick😊, first, we know that, the interior opposite angle of "angle 125°" is "angle x+ the angle adjacent to the left side of angle x" right ?? 👍 by keeping this in mind, we draw a perpendicular on angle 125° (this perpendicular will intersect both the parallel lines) now by looking carefully on the obtained diagram, we notice that: x + 90° = 125° by further solving it, x = 125° - 90° x = 35° 👍
Easiest of easiest way Hence we know by linear pair angle 1 +angle 2 =180
Wrong sum according to cbse 12 th pattern angle 90 degree is opposite alternate angle because z shape is formed ∆35 +x+125-90 35 ; Cact Each measure 90degree Answer 90 ∆35° Don't provide wrong information 😢😢😢😢😢😢😢😡😡🤬🤬🤬🤬🤬🤬🤬🤬

Thank you
Let the triangle be x a= x b= 90 c= 180-125 = 55 (linear pair) In ∆ABC A+B+C= 180 (Angle sum property) x+90+55=180 x+145=180 x= 180-145 x= 35 Hence, angle A is 35°
Parallel lines left the chat 😂😂😂... Jab exterior angles se hi banana tha to parallel bataya hi kyun 😂😂😂... Waise tha banya hua sahi hi ❤
End moment per this boy is made
A=X, B=90°, C=? C+125=180 C=180-125 C=55 A+B+C=180 X+90+55=180 X+145=125 X=180-145 X=35
Here's a short trick We know that In triangle the exterior angle is always equal to the sum of its opposite two interior angles (GIVEN) 125° ( Exterior angle) One angle is 90°as the line falling on it is perpendicular so 90°+x= 125° x = 125°-90°= 35° = x Simple:)
X=35°
Yeh toh zabardast hai bolne ka tarika thoda 'czual' hai
I have done this. Questions
Kid was looking crazy and his last smile was creepy 😂😂😂😂😂😅😅😅😅😅

It simpli x equal to 125 alternate
180 ° - 125° = 55° ( angle 1 )( linear pair ) 90° ( angle 2 ) Let angle 3 be x Angle 1 + angle 2 + angle 3 =180 ( angle sum property of triangle ) 55 + 90 + x = 180 x = 35°
Mam be like- suno beta last main bolna ye to jabardast hai 🤣
Ans is 35 X=35
in triangle abc let the angle A + B + C is equal to 180 degree angle is equal to X angle b is equal to 90 degree angle C is equal to 125 then the separate the B minus C to find the angle then 90 degree minus 135 is equal to 35
😮😮😮😮😮😮😮
Alternate interior angle
LIKE THIS,THERE ARE ALSO OTHER METHOD AND EASY METHOD TO SOLVE THIS QUESTION
Math is Easy 😊 Right 👍🏻❤
Its better to use transversel concept
X = 35
There are multiple methods to solve. We can use concept of transversal, use angle sum property, we can also use exterior angle property etc
35
Alt. interior angle se bhi ho jata !!
Use properties of parallel lines
55° is the answer chikku
Ma'am 12th ka integration bhi laiye na
X=125° alternate interior angle
125 - 90 = 35 Right Answer
The starting sound😂😂"go"
We can also do it as.. 125+x=180 Then,x=55 And as we know,that there is also 90 degree given So,by angle sum property 55+90+x=180 x=35 Done❤
It gone through my had
State line=180° 180°-90°=90° ; 125°-90°=35° ; Ans=35°
It is so easy
It can be solved also by using 180 interor angle its a common thing i dont thik so the trick is important
As we know that exterior angle and interior adjacent angle sum =180° Hence we subtract 125 from 180 then we get the value of interior adjacent angle then third angle=90° (given) then we use ASP(angle sum property)
35.
X 45°
We dont know that the angle is 90⁰. You cant just assume it 😅
we can find the third angle other than 90 and x by linear pair which will be 180-125=55 then we can use angle sum property of triangle by which it will be 90+55+x=180 145+x=180 x=180-145 x=35
Thank you mam aap hamari bhaut jyada madat kar rahe ho thank you mam ji
Yeh toh Zabardast hai 😂
but here not tell that the angle is equal to 90 degree

Sir lifescience ra chapter 6katru sabu chapter complete karidiantu please sir 😭😭😭😭
Sir awesome explanation
we can also form a linear pair of 125 degrees by which we get 1st interior angle which is gonna be 55 and next by angle sum property we'll get ans 35
Ye toh zabardast also in every video
I got the answer Very simple
You can do it with linear pair and angle sum property also ❤❤❤
180 - 125 = 55 Now 90 + 55 + x = 180 (triangle sum property )
90° - k + 125° = 180° After Solving, k = 35°
If you are taking l ।। M then consider the intersecting line a transverse hence we'll get 125 equals 125 and the shaded part will be 125 - 90 Simple I am from class 7

Right angle is equal to 90° Jo angle L ki tarah shape bnae vo 90° hi hota h ye sab to basic chije h jo sabse pehle chapter shuru hone ke wakt btai jati h😅
Those who all are saying, alternate interior angle property In this sum its not possible As the common touching line of 125° and x must be a transversal
Amazing trick mam
This boy look like a smart😂😂,😡😡
