To estimate the height of a building, two students find the angle of elevation from a point (at ground level) down the street from the building to the top of the building is 40°. From a point that is 250 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 57°. If we assume that the street is level, use this information to estimate the height of the building.

answer: it's a

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.

the answer would be 44.79
