Answer:
(D)x|x is a rational number.
Step-by-step explanation:
Given that:
The universal set, U is the set of rational numbers.
S is the set of integers.
Rational Numbers are numbers in the form , b≠0. They are denoted using ℚ.
The set of Integers on the other hand are the set of all positive and negative whole numbers inclusive of zero. They are denoted by ℝ.
Since the Universal Set is ℚ, the set S∈ℝ⊂ℚ (S is a Subset of the set of Rational Numbers). That is, every element in S is a rational number.
Therefore, every x in S is defined as:
x|x is a rational number.
Answer:
42mm
Step-by-step explanation:
Let the shortest side of the triangle be 5x, the middle side be 6x, and the longest side be 8x.
5x+6x+8x = 159.6
19x = 159.6
x = 159.6 ÷ 19
x = 8.4
Shortest side of triangle (5x) = 8.4 × 5
= 42
Answer:
x=36 degrees
Step-by-step explanation:
Remember that all angles of a triangle must add up to 180 degrees due to the Angle Addition Postulate. So let's plug it in! x+65+79=180
Now you solve, x=180-79-65
x=36!
x=36 degrees
The answer is -77.625
Hope this help.
