Given a triangle with the following angle measures, find the value of the missing angle: ∠1 = 35° and ∠2 = 120°
To find the missing angle, we can use the fact that the sum of the angles in a triangle is always 180 degrees.
Let's call the missing angle ∠3.
∠1 + ∠2 + ∠3 = 180 degrees
Substituting the given values, we have:
35 degrees + 120 degrees + ∠3 = 180 degrees
155 degrees + ∠3 = 180 degrees
Subtracting 155 degrees from both sides:
∠3 = 180 degrees - 155 degrees
∠3 = 25 degrees
Therefore, the missing angle is 25 degrees.
