If the measure of an angle is 13 degrees, find the measure of its supplement

Step-by-step explanation:

Two angles are said to be supplementary if they add up to be  . If the first angle is x and the second angle is y , then :

x  + y =   , together the angle will form a straight line.

From the question , the first angle is   , if the second angle is x, then

x + 13 = 180

x = 180 - 13

x =  

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.
