Find the area of the shape shown below.
hichkok12 [17]

Answer:

26.75 units ^2

Step-by-step explanation:

Since the shape is complex, divide it into 3 right angled triangles and one square. Find the area of these individual shapes first, then fin the sum of these area to calculate the ultimate area of e complex shape:

Triangle 1 = 1/2 x 2 x 5 = 5 units ^2

Triangle 2 = 1/2 x 2 x 2 = 2 units ^2

Triangle 3 = 1/2 x 3.5 x 9 = 15.75 units ^2

Square = 2 x 2 = 4 units squared.

Now add all these up 15.75 + 2 + 5 + 4 = 26.75 units squared.

Hope this helps

What is the center and radius of a circle whose equation is x2 + y2 -2x -6y -5 = 0?
ddd [48]

x²+y²-2x-6y-5=0

x²-2x+y²-6y=5

x²-2x+1+y²-6y+9=5+1+9

(x-1)²+(y-3)²=15

(x-1)²+(y-3)²=(V15)²

-> centre of the circle: C(-1,-3)

-> radius of the circle: V15

What is XY=7a YZ=5a Xz=6a+24 In geometry
Cloud [144]

In light of the fact that point y is the point at which segment xz is divided, the value of the variable an is equal to 4.

<h3>How can I determine what the value of the variable an is?</h3>

Due to the fact that point y divides segment xz into two distinct halves, the following equation may be used to get segment xz's total length:

xz = xy + yz.

The following are the parameters for the test:

xy = 7a. yz = 5a. xz = 6a + 24.

As a result, we need to substitute into the equation and then solve for a.

xz = xy + yz

6a + 24 = 7a + 5a

12a = 6a + 24

6a = 24

a = 24/6

a = 4.
