Two of the sides of a right triangle are 8 and 6 units long. How long is the third side? Find all possible answers.
Lana71 [14]

Answer:

10 units.

2√7 units.

- (or 5.29 units to the nearest hundredth)

Step-by-step explanation:

If the 2 sides are legs of the triangle ( that is they are at 90 degrees to each other) the third side, by Pythagoras  theorem:

=  √(6^2 + 8^2)

=  √100

= 10 units.

The other possibility is that 8 is the length of the hypotenuse, in which case

The third side

=  √(8^2 - 6^2)

=  √28

= 2√7 units.

The general form of a circle is given as x^2 + y^2 + 4x - 12y + 4 = 0.
stepan [7]
If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.

If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.

So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.
