The mass of each book in grams if each box weighs 20 kilograms is 2000 grams

  • Mass of each box = 20 kilograms
  • Total books in the box = 10 books

<h3>Converting kilograms to grams</h3>

1 kilograms = 1000 grams

20 kilograms = 20,000 grams

Mass of each book in grams = 20,000 grams / 10

= 2000 grams

Is Abc A right triangle? (HELP)
ollegr [7]
<h2>Hello There today we will solve your problem</h2>

<em>Response-</em>

<em>ABC is absolutely a right triangle</em>

<em>we can use the pythagorean theorem to solve this</em>

<h3><em>Definitions</em></h3>

Right Triangle - <em>A right triangle or right-angled triangle, or more formally an orthogonal triangle, is a triangle in which one angle is a right angle. The relation between the sides and other angles of the right triangle is the basis for trigonometry. The side opposite to the right angle is called the hypotenuse.</em>

Pythagorean Theorem - <em>In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.</em>

<em>_________________</em>

<em>To use to the Pythagorean Theorem it is</em>

A^2+B^2=C^2

For our equation A would be 12 B would be 5

<em>_________________</em>

<h2><em>Solve</em></h2>

12^2+5^2\\144+25\\169\\C^2=169\\C=13

Since we got C=13 this is a right triangle since it's what we had before.
