Question 717127: Please help me solve this equation.
i can not solve this question for my homework
it said:
The sides of the right-angle triangle are x,[x+2]and[2x-2]. The hypotenuse is lenght[2x-2]. Find the actual dimensions of the triangle.
My math teacher told me to use Pythagoras Theorem c^2 = a^2+b^2 but i not sure about that.
Thank you for your help.

Question 717423: Two Telephone Poles 22 feet and 29 feet are 70 feet apart, how long is the wire from the top of one pole to the top of the second pole. Wouldnt you account for the fact that one pole is 7 feet taller than the other and use that as leg A and then we know the base is 70 so that would be leg B, then solve for C at 70.35? is that correct?

Question 726436: Hello,
Thanks in advance for helping me out with this math problem. I am glad there is someone out there who enjoys helping students on their assignments.
The problem is as followed-
Each year in an ancient land, a large river overflowed its banks, often destroying boundary markers. The royal surveyors used a rope with knots at 12 equal intervals to help reconstruct boundaries. Explain how a surveyor could use this rope to form a right angle. (Hint: Use the Pythagorean triple 3,4, and 5)
Thank you once again....
I understand you would want to know what I think of this problem so far. I think one of the lengths of one ray of the angle is 3 and the other is 4. If it were a triangle the hypotenuse would be 5. However, once I read my answer it doesn't make sense... I know 3 times 4 equals 12? I don't know... Please help. Thank you so much

Question 736279: a walkway forns the diagonal od a square playground. The walkway is 24m long. To the nearest tenth of a meter, how long is a side of the playground?
I did:
x ^2 + x^2 = 24^2
x^4 = 576
x= 4.89 m
but then x^2+x^2 does not equal 24^2
plus the book says the answer is 17 m

Question 738322: Want to make a kite using two rods with fixed length : one of 60cm and one of 40cm.Want to ensure the angle at top corner ( angle ABC ) is a right angle.How far down the rod must you affix the the shorter rod(BE)?
2) What is the smallest available size of material that would be large enough to cut kite shape in 1 whole piece?( Sizes available are squares : 20,40,60,70cm?
3) You want to cut the kite shape out of the square with the top corner(B) aligning with the corner of the square.How far along the side of the square from that corner will you need to cut(to 2 significant figures)?
4)What angle do you need to cut into material?
Please could you help me?
Much Appreciated!!
