Un avion vuela en linea recta entre las ciudades A y B que distan entre si 80KM. En determinado momento, las visuales desde el avion a A y B forman angulos de 30 y 45 ¿ a que altura esta el avion en ese instante?

8496 cars

step-by-step explanation:

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.
