What are the coordinates of the circumcenter of the triangle? show your work < 3

We need to find the Circumcenter of the triangle.

Circumcenter could be found by drawing perpendicular bisector of two segments of a triangle.

We have AB a vertical line. So the slope of the vertical line is undefine and slope of perpendicular line to that line would be 0.

We need to find a mid-point between A and B points.

The coordinates of A and B are

A( -2,-5) and B(-2,-2).

So, the Midpoint would be

So, the equation of perpendicular line of AB would have slope 0 and it would be

Now, let us find perpendicular bisector line of AC.

We have coordinates of A and C points as

A(-2,-5) and C(7,-5)

So, the Midpoint would be

So, the equation of perpendicular line of AC would have slope undefined and it would be

So, the intersection point of lines x=2.5 and y=-3.5 is (2.5, -3.5).

answer: i don't understand it

step-by-step explanation: sorry

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
