I need help with setting up a problem. It says: A helicopter spots two landing pads in opposite directions below. The angle of depression to Pad A and Pad B is 46° and 16° respectively. If the straight-line distance from the helicopter to Pad A is 5 miles, find the distance between the landing pads.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

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.
