What you have described is a right angled triangle with a hypotenuse of length 13 feet and a base of 5 feet. To find the length of the remaining side (i.e. how far up the side of the building the ladder reaches) you have to use Pythagora's Theorem. This states that the hypotenuse squared is equal to the sum of the squares of the other two sides. So your answer should be 13^2=5^2+(how far up the side of the building the ladder reaches)^2, which becomes 169=25+(other side)^2, =169-25=(other side)^2 = 144= (other side)^2, so the height that the ladder reaches up the side of the building equals 12 feet.
Using Pythagoras' theorem it is 20 feet
It is called listing when a boat leans. If the boat leans to port (left) then it is listing to port.
A rhombus.
The triangle on top is smaller than the one on the bottom. The reason for this is to have more surface area on the bottom, so the kite leans into the wind. If both triangles were the same size, the kite would lay horizontal (level) and the wind would not lift the kite up. It is a vector problem.Here is a good site to see the physics of kite flyingwww.real-world-physics-problems.com/physics-of-kite-flying.htmlThe kite leans into the wind. So when the wind blows horizontal, the kite is pushed up (lift) and to the right (drag). By adjusting the position of the 3 strings, you can control the stability of the kite.
scalene (it leans)also theres equilateral(3 equal angles/side lengths)and isosceles (looks like an icicle, has 2 equal sides and angles)
30 feet. And you don't have to round it to the nearest foot. It's exactly 30 feet.

The ladder forms a right angle with the building: the ground and the building forming the right angle and the ladder forming the hypotenuse. If the length of the ladder is L metres, then sin(49) = 12/L So L = 12/sin(49) = 15.9 = 16 metres.

If you are asking, what's the distance (x) from the bottom of the ladder to the wall, then... x squared + 2 squared = 3 squared x squared + 4 = 9 x squared = 5 x = the square root of 5, or approx 2.24 m

The Leaning Tower of Pisa.
Assuming the wall is vertical, the wall, the ground and the ladder form an isosceles right-angled triangle. Pythagoras tells us that the square of the length of the ladder, in this case 225 equals the sum of the squares of the other two lengths, ie the height where the ladder touches the wall and the bottom of the ladder's distance from the wall. As these distances are equal in an isosceles triangle each must be the square root of (225/2) ie sqrt 112.5 which is 10.6066, as near as makes no difference to 10 ft 71/4 inches

Brian makes a ladder by cutting down saplings and tying them together with the help of his shoelaces and pieces of his outer shirt. He arranges the saplings like rungs and leans the ladder against the cliff to climb up.
