Answer:

12 sq. units

Step-by-step explanation:

We can see two pairs with same x- or y- coordinates. It means this is a rectangle.

It has sides:

12 - 6 = 6 units and
3 - 1 = 2 units

The area is:

6*2 = 12 sq. units

Answer:

£151.20

20%= 100%divided by 5

To find 100% from 20% you x by 5

so you times 30.24 by 5

30.24x 5 = 151.2

So the answer is £151.20

interest percentage rate would be 1.6754%

The equation cos−1 = x can be used to determine the measure of angle BAC.

Sergio [31]

we know that

in the right triangle ABC

the value of cosine of angle x is equal to

$cos(x)=\frac{AC}{AB}$

we have

$AC=3.4\ cm\\AB=10\ cm$

substitute the values

$cos(x)=\frac{3.4}{10}=0.34$

Find the measure of angle x

$x=cos(x)^{-1} =arc\ cos(0.34)=70.12\°$

Round to the nearest whole degree

$x=70\°$

therefore

the answer is

$70\°$

If the sum of the interior angle of a polygon is 1800 how many sides does it have

Verdich [7]

Answer: 12 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is 180(n-2), where n is the number of sides

$180(n-2)=1800\\\\n-2=10\\\\n=12$
