Answer 1

Answer 2

Hello Karen...This is Jon

Do you have an image of these triangles?

Are the triangles proportional?

The information about these triangles is very limited and to answer this question, one would have to make a number of assumptions.

Such as:

Is ΔABC similar to ΔDEC?

Is line AC (which is 20 meters) similar to the same line on ΔDEC?

Is line AC one of the legs of ΔABC or is line AC the hypotenuse of ΔABC?

What information you provide leaves a great deal of missing information.

Is there any more information provided or an image?
