Answer: The answer to your question is 6\sqrt{3}

Step-by-step explanation:

To solve this problem we will use proportions. We will compare the largest right triangle and the medium size triangle.

                          Medium triangle                     Large triangle

hypotenuse                 y                                            9 + 3

adjacent size               9                                               y

- Write the proportions

                                  y/9 = (9 + 3)/y

-Solve for y

                                  y² = 9(12)

                                  y² = 108

                                  y =   \sqrt{180}

-Find the prime factors of 108

                                  108  2

54 2

                                     27 3

                                      9  3

                                      3   3

                                       1

then,       108 = 2² 3³

-Expressthe root as fractional exponents

                                  2²/² 3²/² 3¹/²

-Simplification

                                   2(3)(3)¹/²

-Result

                                      6\sqrt{3}

Write the equation of the circle with the given graph.
lara [203]

By identifying the radius and the center, we concluded that the equation is something like:

(x - 2)^2 + (y - 1.5)^2 = 1.8^2

<h3></h3><h3>How to write the equation of the circle?</h3>

For a circle centered on the point (a, b) with a radius R, the equation is:

(x - a)^2 + (y - b)^2 = R^2

So first we need to identify the center, we can see that it is: (2, 1.5)

And the radius is the distance between the center and the edge.

R  = 1.8 (measured with a ruler, respecting the notation of the graph).

Then the equation of the circle is something like:

(x - 2)^2 + (y - 1.5)^2 = 1.8^2
