What is the approximate side length of the square if the diagonal is 3?
Alja [10]

Answer:

Step-by-step explanation:

The diagonal of a square is the same thing as the hypotenuse of a right triangle.  This right triangle is a 45-45-90 since the sides are made up of sides of a square which all measure the same length, x.

Using Pythagorean's Theorem,

x^2+x^2=3^2  and

2x^2=9  and

x^2=\frac{9}{2}  and taking the square root of both sides gives us that

x=\frac{\sqrt{9} }{\sqrt{2} }  which simplifies to

x=\frac{3}{\sqrt{2} }  I'm assuming that your teacher has told you about rationalizing the denominator when you've got a radical there, so we will do that by multiplying by  \frac{\sqrt{2} }{\sqrt{2} } :

x=\frac{3}{\sqrt{2} }*\frac{\sqrt{2} }{\sqrt{2} }  which gives us

x=\frac{3\sqrt{2} }{2}

82<br> R5<br> 6<br> ,92 5<br> 4 8<br> 12<br> 12<br> 0
Zarrin [17]

Answer:

  see below

Step-by-step explanation:

The first subtraction has a zero result (blue) from the thousands digit, so we know the dividend has 4 in that place. The 5 in the 1s place of the dividend is brought down to fill the space on the bottom line. 6 goes into that number 0 times, so the final quotient digit is 0.

  4,925 = 6×820 +5

or

  4,925 ÷ 6 = 820 r5
