The measure of the angle formed at the center of an oxygen atom in a water molecule k about 105 degrees . The angles formed at each hydrogen atom are congruent . What is the size of the angle at each hydrogen atom ?

Respuesta :

Answer:

37.5 degrees

Step-by-step explanation:

Congruent angles are the ones that are the same in value, in the attached image we can see the atom, the O atom forms 105 with both H atoms, if we use trigonometry we have

x+x+105=180

x=37.5 degrees the angle
