Find the length of side x in simplest radical form with a rational denominator

Yakvenalex [24]

Answer:

x = √(10)/2

Step-by-step explanation:

Here, we want to get the measure of the side marked x

what we have is an isosceles right triangle since the two acute angles of the right triangle are 45 degrees each

Hence, the other last side will measure x too

Mathematically, according to Pythagoras’; the square of the hypotenuse equals the sum of the squares of the two other sides

Thus;

x^2 + x^2 = (√5)^2

2x^2 = 5

x^2 = 5/2

x = √(5/2)

x = √5/√2

Rationalizing the denominator;

x = (√2 * √5)/(√2 * √2)

x = √10/2

What is the value of 5 in 756

BartSMP [9]

7: has a value of 7 hundreds (or 700)
5: has a value of 5 tens (or 50)
6: has a value of 6 ones (or 6)

5 has a value of 50 or five tens

I believe you would draw this by drawing something that looks like place value blocks. I have attached an example of that. In the ones column, you will have 6 single blocks
