The endpoints of a diameter of a circle are (-4,
aliya0001 [1]

<u>Answer:</u>

<h2>(4, 6)</h2>

<u>Explanation:</u>

x = -4 + (12 - (-4))/2

x = -4 + (12+4)/2

x = -4 + 16/2

x = -4 + 8

x = 4

y = 2 + (10 - 2)/2

y = 2 + 8/2

y = 2 + 4

y = 6

the coordinates of the center of the circle: (4, 6)

  • [Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

<u>Step 1: Define</u>

We are given a right triangle. We can use PT to solve for the missing length.

<u>Step 2: Identify Variables</u>

Leg <em>a</em> = 6

Leg <em>b</em> = <em>x</em>

Hypotenuse <em>c</em> = √89

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Set up equation:                    6² + x² = (√89)²
  2. Isolate <em>x</em> term:                        x² = (√89)² - 6²
  3. Exponents:                             x² = 89 - 36
  4. Subtract:                                 x² = 53
  5. Isolate <em>x</em>:                                 x = √53

180:60 in its simplest from
kipiarov [429]

Answer:

3:1

You can easily figure out that 60 is a factor of 180 bc 6 is a factor of 18.

So you can simplify it to 18:6

Then divide both sides by 6 and you will get 3:1

Hope this helps ;)
