1. ## The Pythagorean Theorem

1. calculate the area of the triangular fields, and the length of perimeter fencing required to secure the site.

AB= 20m, Angle ABC= 60 degrees, Angle ACB= 20 degrees and angle BCD= 60 degrees.

2. ## Re: The Pythagorean Theorem

A triangle has three corners, which I assume you are calling A, B and C. What is D? And what does this have to do with the Pythagorean Theorem?

3. ## Re: The Pythagorean Theorem

I'm sorry mate, it was supposed to be trigonometry, and it basically 2 triangles together, so AB is one side, ABD is the long side and DBC connects back to A of that makes any sense.
I've attached the questions above

5. ## Re: The Pythagorean Theorem

You have mislabeled your diagram - angle BAC = 60, but you labeled angle CBD as 60. It also looks like you labeled angle BCA as 70 - why?

First determine angle BAC from sum of angles of triangle ABC = 180.
Then determine length |BC| using law of sines, since you know angles BAC and ACB, and length |AB|.
Now you can find lengths |AB| and |CD| from basic trig, given angles and length of the hypotenuse |BC|
Finally for triangle ABC you can use the base length of AB and height of BD to calculate its area.

If you post such a messy problem, and are unable to see IT IS messy,
then you require serious classroom help; even a face to face tutor.

Hi DenisB, the reason the question was wrong was because I didn't upload the photo before I posted this thread, and it's not messy once you see the photo you'll understand it much better and clearer
