Answer:

x = 49

Step-by-step explanation:

The third side of the largest of the inner triangles:

= $\sqrt{(7\sqrt{(33)^{2} }- (33)^{2}$

= $\sqrt{528} =\sqrt{(16)(33)} =4\sqrt{33}$

The side that continues next to 33: x -33

Applying similarity property on right triangles:

$\frac{33}{4\sqrt{33} } =\frac{4\sqrt{33} }{x-33}$

$(33)(x-33)=(4\sqrt{33} )^{2}$

$33x-1089=528$

$33x=528+1089$

$x=\frac{528+1089}{33} =49$

Hope this helps

The diameter of Circle Q terminates on the circumference of the circle at (3,0) and (3,-7) . Write the equation of the circle in

Deffense [45]

Step-by-step explanation:

The center of a circle with 2 end points of a di diameter is the midpoint of the two endpoints.

The formula needed to find the minpoints is

(x,y) = (x2 + x1)/2, (y2 + y1)/2

x2 = 3

x1 = 3

y2 = 0

y1 = -7

midpoint = (3 + 3)/2, (0 - 7)/2

midp[oint = 3,-3.5

The midpoint is the center of the circle. Observe that the signs get changed when entering the values for (x,y)

So far what you have is (x - 3)^2 + (y + 3.5)^2 = r^2

To determine r^2 you need only take the distance from the center to oneof the endpoints.

r^2 = (3 - 3)^2 + (3.5 - 0)^2

r^2 = 3.5^2

r^2 = 12.25

Answer: (x - 3)^2 + (y + 3.5)^2 = 12.25
