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 ?

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

x = -2

y = 848

step-by-step explanation:

plug in the numbers

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
