1 answer:

7 0

X^2 + y^2 -4x27 (the numbers in bold means the multiplying a negative and a positive equals a negative)

x^2 + y^2 -(4x27) = x^2 + y^2 -108

The law of cosines states that, if $\alpha$ is the angle between sides b and c,

$a^2 = b^2+c^2-2bc\cos(\alpha)$

So, plugging our values, we have

$a^2 = 16+16-2\cdot 4\cdot 4\cdot\cos\left(\dfrac{\pi}{4}\right)$

This is equal to

$a^2 = 32-32\cdot\dfrac{\sqrt{2}}{2} = 32-16\sqrt{2}$
