Answer:

y = 6 \sqrt{3}  \: units

Step-by-step explanation:

In order to find the value of y, first we need to find the length of the perpendicular dropped from one of the vertices of the triangle to its opposite side.

By geometric mean theorem:

Length of the perpendicular

=\sqrt{9\times 3}

=\sqrt{27}\: units

Next, by Pythagoras theorem:

{y}^{2}  =  {9}^{2}  +  {( \sqrt{27} )}^{2}  \\  \\  {y}^{2}  = 81 + 27 \\  \\  {y}^{2}  = 108 \\  \\ y =  \sqrt{108}  \\  \\ y =  \sqrt{36 \times 3}  \\  \\ y =  \sqrt{ {6}^{2}  \times 3}  \\  \\ y = 6 \sqrt{3}  \: units

Answer:

The circumference is 18.84 inches.

Step-by-step explanation:

To find the circumference of the circle we can use the formula:

C=2\pi r

Where C is circumference and r is radius.

Now that we have the formula, we can substitute the numbers:

C=2(3.14*3)\\C=2(9.42)\\C=18.84

Match this system of linear equations to the correct description of its solution set.
Misha Larkins [42]

Answer:

Infinite number of solutions.

Step-by-step explanation:

Are the equations written correctly?  They are identical.  Since they overlap, every point is a solution for as long as the lines reach.  Since no one is stopping them, the answers are infinite.
