Question

The Two Angles Of Traingle 45° And 60° Find The Measurment Of The Third Angle.

Answer 1

Answer:

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

1st angle = 45°

2nd angle = 60°

3rd angle = x

Sum = 180°

45° + 60° + x = 180°

105° + x = 180°

x = 180° - 105°

x = 75°

Hence the third angle is of measure 75°

Answer 2

${\huge{❥{Ans}{wer}}}$

Two angles of triangles is :-

1st angle = 45°

2nd angle = 60°

3rd angle = y

Solution :-

1st + 2nd + 3rd = 180°

45° + 60° + y = 180°

105° + y = 180°

y = 180° - 105°

y = 75°

Therefore 3rd angle is 75°
