Applying the triangle sum theorem, the value of c in the triangle is: D. 95°
What is the Triangle Sum Theorem?
Based on the triangle sum theorem, the sum of all interior angles in a triangle equals 180 degrees.
Applying the triangle sum theorem, we have:
b = 180 - 45 - 80 = 55°
a = 180 - 100 - 50 = 30°
c = 180 - b - a = 180 - 55 - 30
c = 95°
Therefore, applying the triangle sum theorem, the value of c in the triangle is: D. 95°
