i need help solving my trigonometry question sin45°=10x

Can you find the sine of 45 degrees somewhere, like in a book, or on
a calculator, or on line, or with a pencil and paper ? 

I'd love it if you could draw a picture of a right triangle with legs of
equal length, label the legs ' 1 ', then realize that the acute angles
must both be 45 degrees, then calculate the length of the hypotenuse
and find that it's ' √2 ', then look at your drawing and notice that the
sine of 45 degrees is  " 1/√2 ", which is about  0.707.

But I won't be totally upset if you use your calculator.  Whichever way
you do it, you need to find the sine of 45 degrees, and write it into
your equation.

When you have it, write it into your equation:    0.707 = 10x

Then, divide each side of your equation by 10:    0.0707 = x
