Points C , A , and D are located along the edge of a river and point $B$ is on the opposite edge. Use $\triangle BCA$ and $\triangle BDA$ to determine which of the following are possible widths of the river.

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
