7 0

Answer:

x=12 y=9

Step-by-step explanation:

first we need to do this equation to get X

we don't have y so y=0

x-(0)=12

we eliminate the 0

x=12

now, we have X, now we need to find Y

substitution

x+y=3

12+y=3

y=3-12

y= 9

We need to compute the diagonal of yhe square.

d²=7²+7²=49×2cm²

d=7×sqrt(2)=7×1.41=9.87cm.

The diagonal we just computed is the diameter of the circle that contains the square.

Since d=9.87 < 11, then indeed, the square fits inside the circle, without touching it.

The length of a rectangle is 5.2cm and its breadth is 3.4cm. What is the area of the rectangle?
Rainbow [258]

Answer:

\huge{ \boxed{ \sf{17.68 \:  {cm}^{2} }}}

Step-by-step explanation:

\underline{ \text{Given}} :

\longrightarrow \sf{ \: Length \: of \: a \: rectangle \:  =  \: 5.2 \: cm}

\longrightarrow{ \sf{Breadth \: of \:  \: rectangle \:  =  \: 3.4 \: cm}}

\underline{ \text{To \: find} } :   \sf{Area \: of \: a \: rectangle}

\boxed{ \sf{Area \: of \: a \: rectangle \:  =  \: Length \:  \times  \: Breadth}}

\mapsto{ \sf{Area \:  =  \: 5.2 \: cm \:  \times  \: 3.4 \: cm}}

\mapsto{ \sf{Area \:  =  \: 17.68 \:  {cm}^{2} }}

Hope I helped!

Best regards! :D

What is Pythagoras Theorem ?
Nikitich [7]
Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.
The triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).
Pythagoras is in the form of;
a<em><u /></em>²+b²=c²
However, it can also be written in the form of c²=a²+b²
In order to find the hypotenuse, you will have the length of two sides, for example, these could be 3 and 4.
As 'C' is always the hypotenuse, you have to work out the two other lengths, and you do this by squaring the numbers.
3²=9 and 4²=16.
As you're looking for C, you've got to add these together
9+16=25
As a²+b²=c², this means that the answer for C is the square root of 25.
√25= 5

Hope this has been able to help you :)
