You need the Law of Cosines here, since you only have 1 angle measure.  If you had 2 you could use the Law of Sines, but nevertheless, we'll get there.  The Law of Cosines for our particular set of info looks like this: x^2=65^2+41^2-2(65)(41)cos(35).  Simplifying a bit we get x^2=4225+1681-4366.080396 and x^2=1539.9196.  Taking the square root of that and considering the principle root only, x = 39.2, second choice down.

Find the regular price. Round to the nearest cent . Sales price is 56.78 percent discount is 40%
LenaWriter [7]

100\%-40\%=60\%\\60\% = \frac{60}{100}=\frac{6}{10}=\frac{3}{5}\\\\

Numerator is 3 and denominator is 5. So, we divide the sales price by 3 and we multiply by 5 to get the whole fraction, or 100%.

\frac{56.78*5}{3} \\\frac{283.9}{3} \\94.6333333333333...

Your regular price sounds recurring, so you might have made a mistake copying.

The answer for what you've got is 94.633333...
