The centre of the circle is the middle of the two endpoints
so centre M is M(1,2) so the two last options aren't valid since those would be M(1,-2) and M(-1,2)
The radius would be half the distance of the two endpoints so
√(1+2)^2+(2-1)^2
√9+1
√10
so the answer is the second one

Answer:

$x = \sqrt 6$

Step-by-step explanation:

Given

The attached triangle

Required

Find x

Considering angle 30 degrees,

$Opposite = \sqrt{2$

$Adjacent = x$

Using the tangent formula:

$tan\ 30 = \frac{\sqrt 2}{x}$

Make x the subject

$x = \frac{\sqrt 2}{tan\ 30}$

$x = \frac{\sqrt 2}{1/\sqrt 3}$

$x = \sqrt 2 * \sqrt 3$

$x = \sqrt 6$
