    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

    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 💯

    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° 👍

    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:)
