Question

Can someone please help me?????

Answer 1

Answer:

8

Step-by-step explanation:

To solve for ED, create proportion between the two similar triangles.

$\frac{Big Side}{Big Side} =\frac{little side}{little side}$

where Big represents the bigger triangle an little represents the smaller triangle.

$\frac{2x+4}{9}=\frac{x+4}{6}$

Cross multiply and solve for x.

9(x+4)=6(2x+4)

9x+36=12x+24

9x+36-24=12x+24-24

9x+12=12x

9x-9x+12=12x-9x

12=3x

4=x

Lastly substitute the value into ED which is x+4.

4+4=8
