Oh I think the guest wants to say that this calculator widget/forum is good?

Oh я думаю что гость хочет сказать что этот виджет калькулятора/форум хорош?

Да, пожалуйста, расскажите! Стремясь услышать!

It's funny how I just read Melody's post on "What should you consider before answering" and you did exactly that. lol

Well written answer and also appreciate your help in this forum!

Yeah, I misread the problem (my bad)! 

Thanks for the correction.

So we have this quadrilateral, which has a total of 360 degrees. So. 2 are 90 degree angles, so 180 degrees. 360-180 = 180.

15x+8 + 10x - 3 = 25x +5 = 180. Subtract 5 from both sides give 25x = 175. Divide 25 on both sides gives x = 7. 10*7 -3 = 70-3 = 67.

if brand two's is 8x more effective i assume we just multiply 8 by 22 = 176dB.

Hope you buy brand two 22db isn't a lot

EDIT: Caffeine corrected my mistake, subtract 22 from 176 = 154db.

And also. (sounds of 176dB are VERY harmful to your hearing, strongly suggest you don't take the risk)

SInce it's isoceles, and the different angle is 2 times the base, let's represent these angles using the variable a. the top is 2a, the bases are a. a+a+2a = 4a, so 180/4= 45. Yes. Angle Y is 90 degrees, angle Z is 45, and XZ's perpendicular bisecrotr creates 2 smaller ones due to process of elimination

Using verticle? i think thats the name... verticle angles mean that the angle beneath 45 is also 45, the one sidways up above 75 is 75, so 180-75-45 = 180-120 = 60. And now we add 60 to 79, and subtract that from 180, since it's a line, and get 41, and 180-68-41 = 71. 180-71 = 109.  That's your answer

I'm afraid I don't understand the meaning of "9,5:20 step by step".

Temo di non capire il significato di "9,5:20 passo a passo".
