Need asap ~ what is the value of x assume that the line is tangent to the circle

70

Step-by-step explanation:

An angle on the circle is half of the intercepted arc. Since the circle is 360, you can subtract 220 from 360 and find the intercepted arc which is 140. Divide that by 2 and you get 70.

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.

step-by-step explanation: it is d
