Question

If two angle of triangles are 30 and 105 then the third angle will be

Answer 1

Answer:

the third angle is 45degrees

Answer 2

Answer:

The sum of all angles of a triangle is 180°.

Let the third angle be x.

Then, 30° + 105°+ x = 180°

135° + x = 180°

x = (180 - 135)° = 45°

Hence, the third angle is 45°.
