With a right triangle you can use the Pythagorean formula. a^2 + b^2 = c^2
We will call the hypotenuse c and the leg a
15^2 + b^2 = 39^2 ( rearrange )
b = sqrt of 39^2 - 15^2
= 36
the length of the other two sides is variable.
Let's step through this one and knock it down. Draw a circle and a chord. Now add a radius to the circle that bisects the chord. It will form right angles with that chord, right? Yes, it will. Now add another radius from the center to one end of the chord where it intersects the circumference of the circle. You should have a right triangle, and one side is composed of half the length of the chord. The other side is that short segment between the chord and the center of the circle. The hypotenuse of the triangle is the radius of the circle, which is the last thing we drew in. Now let's do the math à la Pythagorus. You remember him. The sum of the squares of two sides of any right triangle is equal to the square of the hypotenuse. Yeah, that guy. You know the distance to the chord from the center of the circle. Put that on the drawing. You also know the chord length, and half of that will be the length of the other side of the right triangle you created. You have the lengths of two sides of the right triangle. Now square each side, add them together and take the square root of that to discover the length of the hypotenuse - which is the radius of the circle. Piece of cake. Want a sample problem? Why not. The length of a chord of a circle is 24 units. The chord is 5 units from the center of the circle. Remember our right triangle? It has side lengths of 5 units and 24 divided by 2 or 12 units. The 5 squared is 25 and the 12 squared is 144, and 25 plus 144 equals 169. The (positive) square root of 169 is 13, and our radius is 13 units long. Simple and easy. Just like Pythagoras or any of his students would handle the problem.
a line of symmetry in a shape is the line which reflects on the other side of the shape, so you can get the same side onto the other side from an angle! :D I hope that this has helped!
The Black Triangle is an area along the Czech, Polish, and East German borders. This area lost 90 % of the forests due to coal mining and other large industries.
Yes, it does, as does everything that burns, as oxygen is one part of the "Fire Triangle", which is the three things anything needs to burn. The other two components of this triangle are: Fuel and Heat.
Use the hypotenus theorem. the side opposite the right angle squared is equal to each of the other 2 sides squared and then added together
if you're looking for the hypotenus, the answer is 11.4 (rounded to the 100ths place) if you are looking for one of the other sides, the answer is 7.07 (rounded to the 100ths place) hope this is what you were looking for
Divide the length of a side of one triangle by the length of the corresponding side of the other triangle.
The other leg length is 16.
right triangle
The approximate length of the other leg of the triangle is: 11.9 inches.
-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]
Area of a right triangle = (1/2 the length of one leg) x (length of the other leg)
They are triangles. An isosceles triangle has two sides that are equal length, and the other side would be a different length. A right triangle could be an isosceles triangle. On the other hand, a scalene triangle has all of its sides different lengths.

The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
