Angles are not measured in inches, they are measured in degrees. It appears you may be asking about a RIGHT triangle of which two sides measure 4 inches and 5 inches. In such a case, if the hypotenuse measures 5 inches, the third side would measure 3 inches....a 3,4,5 right triangle.
It is a right angle triangle and the 3rd angle will measure 30 degrees
57.5 degrees
The third angle is 34.5 degrees
25 degrees
If you mean an equilateral triangle then the 3rd angle is 60 degrees
It is a right angle triangle and the 3rd angle will measure 30 degrees
It is a right angle triangle.
It is a right angle triangle and the 3rd angle will measure 30 degrees
No because it does not comply with Pythagoras' theorem for a right angle triangle.
The missing angle measure is 100 degrees.
The third angle measures 18 degrees.
20 degrees
105
77 degrees
Each interior angle of an equilateral triangle measures 60 degrees
Each angle measures 60 degrees
57.5 degrees
