Find the area of the square

Mathematics
2 answers:
butalik [34]2 years ago

Answer:

13 units^2

Step-by-step explanation:

one side of the square =

AD^{2} = 2^{2} +3^{2}

AD^{2} =13

AD = \sqrt{13}

So area of square = Length * Length

= \sqrt{13}*

= 13

Answer:

\huge\boxed{\sf  13}

Step-by-step explanation:

Firstly finding the side lengths of the square by Pythagoras Theorem since the base and perpendicular of the triangle is given and hypotenuse is to be found which is also the side length of the square.

<u>Pythagoras Theorem is:</u>

(Hypotenuse)^2=(Base)^2+(Perpendicular)^2

Where, base = 2, perpendicular = 3

(H)² = (2)² + (3)²

(H)² = 4 + 9

(H)² = 13

Taking sqrt on both sides

H = 3.6

All the sides have to be 3.6 since its a square.

Now,

<u>Area of the square:</u>

= Length × length

= 3.6 × 3.6

= 12.9

≈ 13

\rule[225]{225}{2}

Hope this helped!

From a box containing 10 cards numbered 1 to 10, four cards are drawn together. The probability that their sum is even is 21 21
ankoles [38]

Answer:

Step-by-step explanation:

We know that between 1 to 10 there are 5 even and 5 odd numbers.

We could get 4 even cards , 4 odd cards or 2 odd and 2 even cards

Let´s check all this combinations

Case 1: When all 4 numbers are even:  

We are going to take 4 of the 5 even numbers in the box so we have

5C4=5

Case 2: When all 4 numbers are odd:  

We are going to take 4 of the 5 odd numbers in the box, so we have

5C4=5

Case 3: When 2 are even and 2 are odd:

We are giong to take 2 from 5 even and odd cards in the box so we have

 

5C2 * 5C2

Remember that we obtain the probability from

\frac{Number-of-favourable-Outcome}{Total-number-of-outcomes}

So we have the number of favourable outcomes but we need the Total cases for drawing four cards, so we have that:  

We are taking 4 of the 10 cards:

10C_4=210

Hence we have that the probability that their sum is even

\frac{5+5+100}{210}=\frac{11}{21}

Find the values of x and y that make k || j and <br> m || n.
telo118 [61]
Same side interior angles CONVERSE also called consecutive interior angle CONVERSE.
IF  (x - 30) + (x + 50) = 180 then, line line n || m.

x -  30 + x + 50 = 180
2x + 20 = 180
subtract 20 from both sides
2x = 160
divide both sides by 2
x = 80

IF (x - 30) + y = 180, then k || j.
(80 - 30) + y = 180
50 + y = 180
subtract 50 from both sides
y = 130

dem82 [27]

Answer:

a) 0.6435 radians

b) 80.1 feet/sec

Step-by-step explanation:

a) 75 = (50²/16)sin(theta)cos(theta)

sin(theta)cos(theta) = 0.48

2sin(theta)cos(theta) = 0.96

sin(2theta) = 0.96

2theta = 1.287002218

Theta = 0.6435011088 radians

b) 200 = (v²/16)sin(0.75)cos(0.75)

6416.072347 = v²

v = 80.10038918 feet/sec
