Answer: She needs 10 1/2 hours to read the book.
Step-by-step explanation:I day = 1 3/4 hours
6 days = 1 3/4 x 6
6 days = 7/4 x 6
6 days = 42/4
6 days = 10 1/2 hours
The sum of the measures of the interior angles of the chess board is equal to 720°.
<h3>What is a polygon?</h3>
A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides. Also, some examples of a polygon include the following:
- Triangle
- Quadrilateral
- Pentagon
- Hexagon
- Heptagon
- Octagon
- Nonagon
<u>Note:</u> The number of sides (n) of a hexagon is 6.
In Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:
Sum of interior angles = 180 × (n - 2)
Sum of interior angles = 180 × (6 - 2)
Sum of interior angles = 180 × 4
Sum of interior angles = 720°.

Answer:
the side XY
Step-by-step explanation:
we know 2 angles in a triangle. but are 45 degrees.
that means the third angle Z is 180-45-45 = 90 degrees.
the side opposite of the largest angle is the longest side.
opposite of Z is the side XY.
The percentage is 85 percent
Words that came from the same ancestral language and originated from the same word are called COGNATE WORDS.
In linguistics, cognates are words that have a common etymological origin. These are words in two languages that share a similar meaning, spelling, and pronunciation. For an instance, English words have lots of related words in Spanish.
