Answer:
NO X belonging to real numbers is not a close subset
Step-by-step explanation:
The closed interval [a, b] contains all of its boundary points, while the open interval (a, b) contains none of them. We generalize these terms to sets in Rn: A set S is open if S = Sint . A set S is closed if S = ¯ S .

(D) 80°, 140°, and 70° group of segments cannot form a triangle.
<h3>
What is a triangle?</h3>
- A triangle is a three-edged polygon with three vertices.
- It is a fundamental shape in geometry.
- Triangle ABC represents a triangle with vertices A, B, and C.
- In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.
- In other words, the triangle is contained in just one plane, and every triangle is contained in some plane.
- There is just one plane and all triangles are enclosed in it if the entire geometry is merely the Euclidean plane; but, in higher-dimensional Euclidean spaces, this is no longer true.
To find which group of segments cannot form a triangle:
- 80°, 140°, and 70° cannot form a triangle because the sum of the three angles is 290°, whereas the sum of the angles in a triangle is 180°.
Therefore, (D) 80°, 140°, and 70° group of segments cannot form a triangle.

Answer:
0.4 meters
Step-by-step explanation:
The volume is ...
V = LHB
12.8 m³ = (8(5B))(5B)(B) = 200B³ . . . fill in given values
0.064 m³ = B³ . . . . . simplify
∛0.064 m = B = 0.4 m
The breadth of the wall is 0.4 meters.
Answer:
1/6
Step-by-step explanation:
1st spin:
1 out of the 5 sections are pink, so the probability of spinning a pink on the 1st spin is 1/5.
2nd spin:
5 out of the 6 sections are not pink, so the probability of spinning a pink on the 2nd is 5/6.
Multiply the probabilities of the two spins to get the answer.
