TRULY IN NEED OF HELP PLEASEE

x=10
y=7.5
CE = 6
BD=4.5

Explanation:
Use similar triangles. Since you know one side length of the larger triangle, divide it by the hypotenuse of the smaller triangle to get the factor you are multiplying you side lengths by.

12.5 / 5
= 2.5

Multiply every other side length by 2.5

4 x 2.5 = 10
x = 10

3 x 2.5 = 7.5
y = 7.5

To get CE and BD subtract your values:

CE = 10 - 4
CE = 6

BD = 7.5 - 3
BD = 4.5

Yes of course i will indeed you with your problem.

Gotta be d the music of previous eras
