<h2><u>Given</u>:-</h2>
Let us assume the three angles to be angle 1, angle 2 and angle 3.
Angle 1 = 35°
Angle 2 = 120°
<h2><u>To</u> <u>find</u>:-</h2>Angle 3.
<h2><u>Solution</u>:-</h2>We know that,
➪ ∠ 1 + ∠ 2 + ∠ 3 = 180°
➪ 35° + 120° + ∠ 3 = 180°
➪ 155° + ∠ 3 = 180°
➪ ∠ 3 = 180° - 155°
➪ ∠ 3 = 25°
∠ 1 + ∠ 2 + ∠ 3 = 180°
✒ 35° + 120° + 25° = 180°
✒ 180° = 180°
