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

[lakhangaming.]

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

[datts-fc-official]

"Yeh toh jabardast h" was epic 😂

[avyayskandahasa]

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

Arey! yahan Kahan aa gayi mein yahan to sare maths ke Topper hai 😅😅
Comments mai bhi OMG! 😎🔥

[Shourya]

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 😅😅😅

[Rishabh_]

Maam but you didn't tell that the angle is 90

[ShashiYadav-cjew]

Also be done by Angle Sum property and co interior angles and alternate interior angles, etc...

[blackpengaming]

180-125=55°(linear pair)
X+90+55=180°(sum of all triangle)
X=180-145
X=35°

[diwamanav_]

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°

[aalokyadav]

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

[AlooMastrang]

The way he said "Yeh to jabardast hai"😂😂😂😂😂

[FactsfromMind]

Let the side angle of triangle be x
so 125+x=180
X=180-125=55
By angle sum property angle x +55+90=180
145+x=180
X=180-145
=35

[bunysao]

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:)

[sujitsingh]

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

[kantaseries]

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)

[AeroidPythoncoder]

180-125=55 (linear pair)
a+b+c=180(triangle angle sum property)
X+55+90=180
X=180-145
X=35 answer

[pratyushchaudhary-kkvg]

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

[Studysquadshorts]

Jab mam aapne bataya ni hai ki 90° hai to aap use nhi maan sakte hai kya pata vo angle 89 bhi ho sakta hai ya 91 bhi ho sakta hai

[phadi_mohit_]

Liner pair = angle x = 180 -125 =55
X=55 ans
