Aquadrilateral with vertices at a(4, –4), b(4, –16), c(12, –16), and d(12, –4) has been dilated with a center at the origin. the image of d, point d1, has coordinates (36, –12). what is the scale factor of the dilation?

it is x=-4

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
