Answer:
48 ft.
Step-by-step explanation:
Since triangles ABC and DEC are similar (you can prove this quite easily), then we know the ratio of the sides are equal. This is a property of similar triangles. So we take the ratio of the sides CE and DE and the ratios of the sidesBC and AB.
We get:
So x is 48 ft.
A= -1
You add the 6a and 5a.
Your equation is then 11a= -11
At this point you divide each side by 11 to get "a" by itself.
