Answer:
28. The difference represents an irrational number
29. The difference represents a rational number
30. The quotient represents a rational number
31. The quotient represents an irrational number
Step-by-step explanation:
* Lets explain how to solve the problem
- The rational number is any numbers can be put in the form of a/b,
where a and b are integers b ≠ 0
- Ex: 1 , 2/3 , 5/4 , 22/7 , 100 , ................
- The irrational number is any number that is not rational
- It is a number that cannot be written as a ratio of two integers
or cannot be expressed as a fraction
- Ex: √2 , √7 , π , ..... (π is irrational because it's approximated value)
- If the part of the the number is irrational, then the number
is irrational
- Ex: (5 + √3) , (√7 + 5) , 2√5 , √11/4 , 5/√13
* Lets solve the problems
28.
∵ √2/2 is an irrational number
∵ One term is an irrational number
∴ The difference represents an irrational number
29.
∵ The two terms are rational numbers
∴ The difference represents a rational number
30. ÷
∵ The two terms are rational numbers
∴ The quotient represents a rational number
31. ÷
∵ √2/2 is an irrational number
∵ One term is an irrational number
∴ The quotient represents an irrational number
Answer:
74°
Step-by-step explanation:
From the attached figure, translation only affects the length of the sides of the triangle :
From the figure :
We are given ;
A = 80° ; C = 26° ; B =?
Sum of angles in a triangle :
A + B + C = 180°
80° + B + 26° = 180°
106° + B = 180°
B = 180 - 106
B = 74°
