Question

In a triangle measure of two angles are 105° and 25° then the measure of third angle of the 3rd angle is?​

Answer 1

sum of angles of a triangle = 180⁰

Let the third angle be = x

105⁰ + 25⁰ + x = 180⁰

130 + x = 180⁰

x = 180⁰ - 130⁰

x = 50⁰

Third angle = 50⁰

Answer 2

Answer:

50 degree

Step-by-step explanation: sum of all the angles of triangle = 180 degree

105 + 25 =130 DEGREE

so 180- 130 = 50 degree
