Question

Find the length of the wtre AC
If BD IS A GROUND OF 60M AND TWO VERTICAL POLES FIXED TO THE GROUND NAMED AB AND CD
AB =55m
CD= 66m

Answer 1

Step-by-step explanation:

ANSWER

We have,

AB=55m

BD=60m

DC=66m

AC=?

AD=24cm.

Construction:- Meet A to any point E line CD.

Then,

AE=60m

DE=AB=55m

Now,

CE=CD−DE

CE=66−55

CE=11m

So,

InΔACE

Using Pythagoras theorem,

AC

+EC

=3600+121

AC

=3721

AC=61m.

Hence, this is the answer.
