Let's say n = the unknown number
then, 3n-25 would be your answer
First you multiply 6 and 14 then you subtract
Answer:
D,E
Step-by-step explanation:
The correct answer is C. Coplanar, line.
The undefined terms are needed to define parallel lines are coplanar and line.
<h3>What are parallel lines?</h3>
Two lines in a single plane that are equally spaced apart and never cross each other are said to be parallel lines in geometry. All horizontal and vertical shapes are possible.
Examples of parallel lines can be found everywhere, including zebra crossings, rows of notebooks, and the nearby railroad tracks.
Some characteristics of parallel lines are-
- They are usually parallel straight lines that are spaced equally apart.
- These lines are coplanar.
- No regardless how far you extend these in any direction, they never come together.
- A transversal line will create four angles at each of its two sites of intersection with two parallel lines if it does so.

Answer:
The angle formed between CF and the plane ABCD is approximately 47.14°
Step-by-step explanation:
The given parameters are;
BC = 6.8
DE = 9.3
∠BAC = 52°
We note that the angles formed by the vertex of a cuboid are right triangles, therefore, by trigonometric ratios, we get;
sin∠BAC = BC/(The length of a line drawn from A to C)
∴ The length of the line drawn from A to C = BC/sin∠BAC
The length of the line drawn from A to C = 6.8/sin(52°) ≈ 8.63
∴ AC = 8.63
By trigonometry, we have;
The angle formed between CF and the plane ABCD = Angle ∠ACF
In a cuboid, FA = BG = CH = DE = 9.3
The angle formed between CF and the plane ABCD = Angle ∠ACF ≈ 47.14°
