Hello Missjay12,
Step 1 :
From the coordinates we have to find the slopes and midpoints of the lines.
Step 2 :
Find the slope of the bisectors and now find the equations of two lines by using slope and one mid points.
Step 3 :
Solve any two pair of equations and find the intersection point.
Step 4 :
The point thus found is the circumcenter of the given triangle.
so<span> the coordinates of the circumcenter of a triangle with vertices A(−3, 3) , B(−1, 3) , and C(−1, −1)</span> is, -4, 0.

Why?
We have the isosceles right triangle. The length of legs are 6. Use the Pythagorean theorem:

In general, the formula for calculating the hypotenuse in an isosceles right triangle is 
a - a leg, h - a hypotenuse
Answer:
95% since 19÷20 is 0.95 which multiplied by hundred is 95
Answer:
It's nine plus negative three
