No problem!

Oh, sorry... 98.......198=49+2=51 multiples of two and 99.....198....33...66, 34 multiples of three. We have to subtract the multiples of 6, 102....198, 17..33, 33-16=17. 51+34-17=68.

We know that it has to be a 30-60-90 triangle based on the info. The cosine of the smallest angle, which is 30 degrees is adjacent divided by hypotenuse, or \(\frac{\sqrt{3}}{2}\) or (C). The \(2x\) came from across the 90 degree angle.

Yes, it's pretty neat!

There has to be rational values on either side of the equal sign.

The shortened version of the formula is: \(|30H-5.5M|\), where \(H\) stands for hours and \(M\) stands for minutes. Thus, we have \(|30(6)-5.5(48)|=|180-264|=\boxed{84}\) degrees.

maybe 1001 base n.

Since this has a tangent and secant, Power Of Point gives us \(9x^2=225, x^2=25, \boxed{x=5}.\)

Correct, Melody, I forgot. I won't do it next time.
