Use the graph to find the coordinates of each vertex in triangle ABC
vis the coordinate of Point A
is the coordinate of Point B.
is the coordinate of Point C

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

b, i believe, but not sure.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

i believe the answer is 323 ft
