A^2 + b^2 = c^2....where a and b are the legs, c is the hypotenuse
3^2 + b^2 = 7^2
9 + b^2 = 49
b^2 = 49 - 9
b^2 = 40.....take sqrt of both sides, eliminating the ^2
b = square root of 40 <==
Sin(2π/3radians) = sin(π/3radians) = (<span><span>√3)/</span>2</span>cos(2π/3radians) =<span> - cos(π/3radians) = 1/2
</span>
becuase 2π/3 + π/3 = <span>π</span>

The answer is D. Trust me.
Slope = (8 -2) / (1 + 5) =6/6 = 1
Parallel lines, slope is the same
So the slope of any line parallel to the line containing (-5,2) & (1,8) is also equal 1
