Question

In Triangle ABC, if sum of two angles is 100°, what is the measure of third angle
?​

Answer 1

Answer:

Ans-80°

Step-by-step explanation:

Sum of all angle of triangle is 180°

For ex:- A+B+C=180°

100 divided by 2 =50

A= 50:B=50

180-100=80

Hope u understand

Answer 2

Answer:

One common property about triangles is that all three interior angles add up to 180 degrees. This now brings us to an important theorem in geometry known as Triangle Angle Sum Theorem. According to the Triangle Angle Sum Theorem, the sum of the three interior angles in a triangle is always 180°.
