Question 57915: The length of one leg of a right triangle is 24 ft. The length of the other leg is 16 ft. shorter than the hypotenuse. Find the length of the hypotenuse and the other leg. Would it be (x-16)^2+24^2=x?? If it is, I'm not quite sure how to solve that.

Question 62354: Right angle triangle that has a line drawn parallel to the base line of the triangle.
The top angle of the triangle is A, the right angle is B, and the last angle is C. There is a line about 2/3 of the way down between A and B, creating D.
This line segment will be called DE it runs parallel to BC.
AD=4, DB=2, BC=8. I figured out that AC=10 using the pythagorean theorem. But I can't figure out how to get DE or AE or EC. I've tried all sorts of equations and can't come up with an answer.

Question 62930: A right triangle is a triangle with one angle measuring 90 degree. In a right triangle, the sides are related by the Pythagorean Theorem, c^2 = a^2 + b^2 where c is the hypotenuse (the side opposite the 90 degree angle). Find the hypotenuse when the other 2 sides' measurements are 3 feet and 4 feet.

Question 63917: Please I need help with this Question using Pythagorean theorem and expressing my answer in the simplest radical form. The triangle I am trying to solve from has a 90 degree angle, a 30 degree angle, and a 60 degree angle. On the side of the 60 degree angle the length of the leg is 10. Now, I have to find the hypotenuse and the length of the other leg, with my anwer in simplest radical form. All I know is  and I have to solve for a & c , but I haven't the slightest clue where to go from there. Can someone please please help???

Question 63928: (-2,1) and (5,-6) solve using the pythagorean theorem
I have tried
d= the square root of (x-x)^2+(y-y)^2
d= the square root of (-2-5)^2+(1-6)^2
d= the square root of (-7)^2+(-5)^2
d= the square root of 49+25
d= the square root of 74
i know this is wrong, especially since i'm supposed to solve using the pythagorean theorem! Please help--thank you!

Question 65021: Hello! I am currently doing a project for an Environmental Science class. We are studying ways to save energy. I have been asked to give the measurements of my home.
I am running into a problem when I try to give the area of the walls and also the area of the ceilings (total). I have 1,100 square feet in my home. It would not be so bad if I had just all 8 ft. ceilings. However, in the 18x13 living room I have a vaulted ceiling reaching 13 feet. (All of the other rooms have 8ft.) I am sure I am just making this difficult. I need to use the Pythagorean Theorem to figure this out, but seem to come up with answers that do not make sense.
Can you help?

Question 67102: I usually am good at this kind of problem, but this one tripped me up a bit! I would really appreciate your help. The question is as follows:
The area of a right triangle is 2. The sum of the length of the two sides adjacent to the right angle is 10. What is the length of the hypoteneuse of the triangle?

Question 70512: in my math class we are supposed to figure out a shorter distance betwen two places in our house using the Pythagorean Theorem.
1) you must decide on two destinations in your house where you must walk from one room to another. These rooms cannont be straight across from each other for the project to be applicable
2)you must draw a neat diagram of this path, showing which way you would walk
3)you must measure the distance walked from one to the other.
4) finally, you must use the Pythagorean Theorem to figure out how far it would be to walk straight from one room to the other without walls.
I measured the distance betwen my two rooms. one way was 19.1 ft. down a hallway then you go left 12.4 ft. and your into the next room. I need help figuring out how to use the Pythagorean Theorem to find out what the
measurments would be if you would just go straight???? please help me the project is due tomarrow
Thank you

Question 70816: Lotsafun Amusement Park has a new ride, th Sky Breaker. The starting and ending points of the ride are seperated by 1000 meters. The tram cars glide along a cable that rises at a 45 degree angle from the ground until it reaches a height of 15 meters. The cable runs parallel to the ground for most of the ride, eventually sloping down again at a 45 degree angle with the ground. How long to the nearesttenth of a meter, is the cable for the Sky Breaker ride?

Question 71503: Steven and Corinne each have GPS units for determining their precis positions. While starting from the same location, Steven heads off in a northeast direction for 180 meters and Corrine heads off in a northwest direction for 350 meters. How far apart are Steven and Corrine?
A 292.4 m
B 330.5 m
C 381.5 m
D 393.6 m
When I tried this problem, I drew a triangle out that was like this (please ignore the dashes and periods.....i put them there so all those spaces would be there and it would look like a triangle):
?
-\------------------|
--\.................|
----\...............|
------\.............| 180
350------\..........|
------------\.......|
---------------\....|
------------------\.|
--------------------\
I then used pythagorean theorem:
a^2+b^2=c^2
180^2+b^2=350^2
32400+b^2=122500
122500-32400=b^2
90100=b^2
300.16662039607268763449850971101=b
If there was an answer that was anywhere near that, I would assume that, but there is no answer less than nine numbers away from my answer.
Please help me!

Question 71488: I am having some problems with a paper that's objective is "To use the Pythagorean Theorem to solve real-life problems." There is one specific problem I am having trouble with. It reads:
A 65-foot tree is cut to a level of 3 feet from the ground. The fallen tree collapses against another tree that is 18 feet away. About how far off the ground does the fallen tree touch the second tree?
The answer choices are:
F 47.8 ft
G 48.7 ft
H 53.9 ft
J 62.3 ft
For some reason and somehow I keep getting 18.3 but apparently I don't have the right answer. Maybe I am setting it up wrong. Please help because my teacher keeps on telling me the same thing when I ask her about this question.
Please Help!!!
