Question The Triangle Angle Sum Theorem states that the sum of the angles inside a triangle must equal 180°. Using this theorem, find the measure of angle B. (1 point) Responses 25° 25° 335° 335° 80° 80° 45°
The measure of angle B can be found using the Triangle Angle Sum Theorem.
Let's denote the measures of angles A, B, and C as A, B, and C respectively.
According to the theorem, A + B + C = 180°.
Given that angle A is 55° and angle C is 50°, we can substitute these values into the equation above:
55° + B + 50° = 180°
Combining like terms, we get:
105° + B = 180°
Subtracting 105° from both sides:
B = 180° - 105°
B = 75°
Therefore, the measure of angle B is 75°.
