Answer:
Step-by-step explanation:
Given: expressions
To find: expression that denotes a rational number
Solution:
A number of the form 
where p and q are integers and 
is said to be a rational number.
Sum of a rational and irrational number is irrational.
In 
, 
is a rational number and

Step-by-step explanation:
Answer:
x = 27
Step-by-step explanation:
line AC and DE are parallels, so the extra angle in the triangle would be 2x because they are corresponding angles.
A triangle adds up to 180, so the equation would be 180 = 72 + 2x + 2x
Answer:
Polygons can be separated into triangles by drawing all the diagonals that can be drawn from one single vertex. If you look back at the formula, you'll see that n – 2 gives the number of triangles in the polygon, and that number is multiplied by 180, the sum of the measures of all the interior angles in a triangle.
