For this, you need the Pythagorean theorem.

Let A equal x + 9

Let C equal 26

A^2 + B^2 = C^2

(x + 9)^2 + B^2 = 26^2

x^2 + 18x + 81 + B^2 = 676

x^2 + 18x + B^2 = 595

This doesn't help you find x, but I hope this did something!

What length of equal sided triangle equals hypotenuse of 42 inches?

An equal sided triangle cannot have a hypotenuse!


The slant height of a pyramid and the altitude of a pyramid are not the same thing?

True, because the slant height and the altitude, or height, of the pyramid form one leg and the hypotenuse of a triangle withing the pyramid, and the hypotenuse of a triangle is always the longest side- it is not possible for the hypotenuse to be equal to the legs of a right triangle. (It is a right triangle because an altitude is perpendicular to the base of a pyramid.)


What median of an isosceles triangle is the same segment in the triangle as the leg bisector hypotenuse altitude?

It is the median which divides the side which is not one of the equal sides.


What is the square of the hypotenuse?

The square of the hypotenuse is equal to the length of the hypotenuse times itself. This is also equal to the sum of the squares of the other two sides in a right triangle.


Is the altitude of an equilateral triangle equal to a side length?

No. The altitude is smaller.

Definition of converse for pythagorean theroem?

Pythagorean Theorem: In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.Converse: If the square on the hypotenuse is equal to the sum of the squares on the other two sides of a triangle, then it is a right triangle.
