Each 2 pi is a trip around the circle and doesn't affect the answer.

15 pi/2 = 6 pi + 3pi/2 so tan(15pi/2) = tan(3pi/2) and that is undefined because sin(3pi/2) = -1

and cos(3pi/2) = 0

and (-1/0) is division by 0 and that is undefined.

.68x = 278    divide both sides by .68

x = 408.824

409 is the answer

what is the square root of 1,157,238,234,098,975,983,094,353,458,450,346,520,740,364 who ever has the correct and verifyed answer will get 5,000 dollars. you must show your work

thank you and welcome back

"An alternative to using semi-log graph paper is to use linear paper. Instead of plotting your linear data vs. the exponential data you would acutally take the log of the exponential data then plot it."

how would you use logarithm to do it?

The basic theorem that's used here is,

' the angle at the centre of the circle is twice the angle at the circumference '.

So, in Q9, the angle at the centre TWV, will be twice the angle at the circumference TUV,

ie. angle TWV = 2 times 67 = 134.

It follows then, that 16x - 10 = 134,

16x = 144,

x = 144/16 = 9.

In Q10, angle KNM = 2 times (7x + 9) etc.

Q's 11 and 12 require a little more thought. Come back if you can't do them, (after you've tried to do them that is). 

Hi LunaMoon,

Yes that is a very good answer.

I'd just suggest that you write one last line:

x=0.2          

The last line shoudl always be         pronumeral = 

Got it 

It is good to see you experimenting and trying things Travisio.
