High school geometry anyone?
i will give brainliest : ) i'm really struggling.

me find the length of ec below, and explain thoroughly. you can round your final answer if you wish.
additional info:
de is parallel to ac.
angle c is 60°.
angle a and angle bde are both right angles.
triangle abc is similar to triangle dbe.
: )

Therefore the length of EC is 6.67 ft.

Step-by-step explanation:

Given:

BC = 12 ft

AC = 6.75 ft

DE = 3ft

DE is parallel to AC.

Angle C is 60°.

Angle A and Angle BDE are both right angles.

Triangle ABC is similar to Triangle DBE.

To Find:

EC = ?

Solution:

Δ ABC ~ Δ DBE ..................Given

If two triangles are similar then their sides are in proportion.

On substituting the given values we get

Now as B - E - C,

..........Addition property

substituting the given values we get

Therefore the length of EC is 6.67 ft.

answer: 20
