There are many pairs of integers (whole numbers) that equal -6.
1 + 5
2 + 4
3 + 3
-3 + 9
You can choose from any of those pairs.
Yes, 2 ≤ x ≤ 5 is an inequality.
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols. When the symbols ">","≤", "≥" or "<" are used to connect two real numbers or algebraic expressions, the relationship is referred to as an inequality.
Following above literature and considering the fact that 5 is always greater than 2 and 2 is always lesser than 5, the given relation can be identified as an inequality.

<u>Given:</u>
A zip line goes from 28 feet to 11 feet in the air. The angle of depression is 85°.
<u>To find:</u>
The length of the zip line where there is no rider.
<u>Solution:</u>
A right-angled triangle can be formed using the given data.
The difference in height between the start and end of the zipline is 
. The angle of the triangle is 85°.
Assume the zip line is x feet long.
The adjacent side of the triangle measures 17 feet, the hypotenuse of the triangle measures x feet, and the angle of the triangle is 85°.
To determine x, we calculate the cos of the given angle.
Rounding this off, we get the length of the zip line when there is no rider is 195.18 feet long.
To figure out the interior angles you multiply the number of sides minus 2 by 180 so for a triangle there are 3 sides so you minus 2 to get 1 multiply it by 180 and you get 180 which is the interior angles of a triangle so to do this one you minus 2 from 6 to get 4 multiply it by 180 and you get 720 degrees
