Assuming you are trying to find what kind of figure this represents, also that this = 0,

x^2 -4x       + y^2 +12y      =20
Completing the square for both x and y,
x^2 -4x +4 + y^2 +12y +36=20 + 4 + 36 = 60
(x-2)^2 + (y+6)^2 = 60
is a circle with center at (-2,6) with a radius of the square root of 60 or 2SQRT(15)

By applying the Tan trigonometric formula, the value of the tangent for angle A is equal to: A. 3√91/91.

<h3>How to find the value of the tangent for <A?</h3>

In order to determine the value of the tangent for <A, we would apply Pythagorean theorem:

AB² = AC² + BC²

40² = AC² + 12²

AC² = 1600 - 144

AC = √1456

AC = 4√91 in.

Now, we can determine the value of the tangent for <A by applying the Tan trigonometric formula:

TanA = Opp/Adj

TanA = BC/AC

TanA = 12/4√91

TanA = 3√91/91.

A circle with radius of \greenD{5\,\text{cm}}5cmstart color #1fab54, 5, start text, c, m, end text, end color #1fab54 sits insid
Marat540 [252]

Answer:

The area of the shaded region is 42.50 cm².

Step-by-step explanation:

Consider the figure below.

The radius of the circle is, <em>r</em> = 5 cm.

The sides of the rectangle are:

<em>l</em> = 11 cm

<em>b</em> = 11 cm.

Compute the area of the shaded region as follows:

Area of the shaded region = Area of rectangle - Area of circle

                                            =[l\times b]-[\pi r^{2}]\\\\=[11\times 11]-[3.14\times 5\times 5]\\\\=121-78.50\\\\=42.50

Thus, the area of the shaded region is 42.50 cm².
