Question 199738: Carpenters and builders will sometimes measure 3 ft from a corner along one wall and 4 ft along the other, then check that it's 5 ft between the 2 points. If it is, the walls are "square", at right angles.
If the two short sides of a building are 3 and 4 how would you show carefully that you used the Pythagorean theorem to calculate the diagonal as 5?

Question 203430: Hi, could you guide me about my mistake?
What are the lengths of sides of an equilateral triangle of height 3 cm?
My solution is:
I regard if I intersect this triangle to two right triangles I can use of following formula which I remember of high school:
Sin alpha = opposite side/hypotenuse
I consider: Sin 60=h/c
So I will have radical1/2= 3/c
therefore c =6 = a = b
but its not ok cause 3^2 +^2 is not equal to 6^2!
one more thing: could you tell me do I can use of Sin alpha = opposite side/hypotenuse
and Cos alpha = adjacent side/hypotenuse for all the angles in a triangle? even for a right angle?

Question 204722: Two isosceles triangles have the same base length. The legs of one of the triangles are twice as long as the legs of the other. Find the lengths of the sides of both triangles if their perimeters are 23 cm and 41 cm.
I haven't done much with this problem because whenever I try to solve I wind up with a weird number. I know that the perimeter of a triangle is P= a+b+c so it would be 41=a+b+c and 23=a+b+c but that is pretty obvious. Please help!

Question 205464: I have a problem that has stumped me that has not been covered in our course material, as far as way the problem is structured. It involves the pythagorean theorum. It asks, if you were to construct a right triangle where the shortest side is 5 feet less than the longest side and 3 feet more than the shortest side, what are the length of all three sides?
I know the formula, but I am confused on how it should be translated. I tried (h-8)^2 + (h-7)^2 = h^2 but I end up with 2 similar factorable polynomials and keep running into prime number 113 and not a quadratic problem. Any help would be great.
