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

All 3 angles = 180...if one angles measures 105, the other 2 have to add up to 75. Since they told us the other to angles are the same (“congruent”), divide 75 into 2 equal parts...75/2=37.5.
So the measure of the other 2 angles are both 37.5

Answer:
I believe that the remaining angles are both 37.5 degrees.

Explanation: The sum of the interior angles of a triangle equal 180 degrees. 180-105= 75. The two remaining angles are congruent. So 75 divided by 2 gives the measurement of each angle. Please tell me if I am correct.
