Is the figure an example of perpendicular lines? A. Yes, the lines intersect at a 90- degree angle B. Yes, the lines do not intersect at a 90-degree angle C. No, the lines intersect at a 90-degree angle D. No, the lines do not intersect at a 90-degree angle.

it is B: yes the lines do not intersect at a 90 degree angle.

Step-by-step explanation:

if it intersected at a 90 degree angle, then it would have the 90 degree angle symbol and the figure would look like a cross, rather than an X shape.

here is an example of a figure that is perpendicular with a 90 degree angle:

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.
