Answer:

5 and -3

Step-by-step explanation:

x+y =2

X-Y=-8

BY USING SIMULTANEOUS EQUATION

SUBTRACT SUCH THAT

2Y=10

SO Y = 5

X= -3

I will give Brainiest if you are right

Vadim26 [7]

Answer:

19.5º

Step-by-step explanation:

Every triangle is equal to 180º for all angles. So, you add 33.5 + 127 and subtract the sum by 180.

33.5 + 127= 160.5

180- 160.5 = 19.5

So, the angle F is 19.5º

Hope this helps !!

What is the area of the shape below

Bad White [126]

Answer:

The area of the shape is $A=886 \:cm^2$ .

Step-by-step explanation:

The shape in the graph is a composite figure is made up of several simple geometric figures such as triangles, and rectangles.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together.

First separate the composite shape into three simpler shapes, in this case two rectangles and a triangle. Then find the area of each figure.

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

The area of the first rectangle is $A=34\cdot 16=544\:cm^2$

The area of the second rectangle is $A=11\cdot19=209\: cm^2$

The area of a triangle is given by the formula $A=\frac{1}{2} bh$ where <em>b</em> is the base and <em>h</em> is the height of the triangle.

The area of the triangle is $A=\frac{1}{2} \cdot 14\cdot19=133\:cm^2$

Finally, add the areas of the simpler figures together to find the total area of the composite figure.

$A_{composite\:shape}=544+209+133=886 \:cm^2$

I don't get it and I have tried it multiple ways

Answer:

9350 m²

Step-by-step explanation:

There are several ways you can go at this. Here are 3 of them:

along an extension of the lower right vertical edge, divide the figure into a rectangle and a right triangle.
between the upper left corner and the inside corner at lower right draw a diagonal line to divide the figure into a trapezoid and a triangle.
subtract the area of the trapezoid at the right from the area of the bounding rectangle

The relevant formulas for area are ...

rectangle: A = LW . . . . . . . . . . . length times width

trapezoid: A = (1/2)(b1 +b2)h . . . b1, b2 are the bases, h is the height

triangle: A = (1/2)bh . . . . . . . . . . . b is the base, h is the height

Here's what those computations look like:

1. rectangle: 60m wide by 80 m high = 4800 m².

right triangle: base 190-60 = 130 m; height = 80-10 = 70 m.

area = (1/2)(130 m)(70 m) = 4550 m²

figure area = 4800 m² +4550 m² = 9350 m² . . . . area of figure

2. The trapezoid has bases of 80 m and 10 m, and a height of 60 m. Its area is ...

A = (1/2)(80 m +10 m)(60 m) = 2700 m²

The triangle has a base of 190 m and a height of 80-10 = 70 m. Its area is ...

A = (1/2)(190 m)(70 m) = 6650 m²

Then the total area is 2700 m² +6650 m² = 9350 m² . . . total area

3. The bounding rectangle is 190 m by 80 m, so its area is ...

A = LW = (190 m)(80 m) = 15200 m²

The (negative) trapezoid at right has bases of 10 m and 80 m, and a width of 190-60 = 130 m. Its area is ...

A = (1/2)(10 m +80 m)(130 m) = 5850 m²

The area of the figure is the difference between these:

figure area = 15200 m² -5850 m² = 9350 m² . . . figure area
