First question : in rectangle ABCD triangle ABE is equilateral triangle CDE is isosceles , with CE=DE D=65degrees
Second question : xsquared=196
3rd question: T=nsquared-12/n work out n when n=5
3(b): why is T is always positive when n is negative
4th question: A straight line has a gradient 4 and passes through the line point (5,23)
Work out the equation of the line give your answer in the form y= mx+c

So - where is your work?

You do realize that length of (Path PQR) = length of (Path PQ + Path PR + Path QR) $$\displaystyle | \ \ \ \ \to \ \ \ \$$ 170 = Path PQ + Path PR + Path QR

Assume length of (Path PR) = x

The problem with the path (PQR) is a problem from another thread.

What is the problem for the OP, with the rectangle ABCD?

Not quite - the poster changed the problem in post #5!

The rectangle was not posted fully!

Yes, but he already has another post with the path thing. I guessed that he posted the wrong question after he was asked for more information.
