Line WS is parallel to line KV. Line RT is perpendicular to line KV. Explain the relationship of line RT to line WS. Provide at least one reason to support your answer.
Please help fast! I'm being timed
Answer:
If [tex]\displaystyle\mathsf{\overline{WS}}[/tex] ║ [tex]\displaystyle\mathsf{\overline{KV}}[/tex], and [tex]\displaystyle\mathsf{\overline{KV}}[/tex] ⊥ [tex]\displaystyle\mathsf{\overline{RT}}[/tex], then [tex]\displaystyle\mathsf{\overline{RT}}[/tex] ⊥ [tex]\displaystyle\mathsf{\overline{WS}}[/tex]
Step-by-step explanation:
We are given the diagram of parallel lines, [tex]\displaystyle\mathsf{\overline{WS}}[/tex] and [tex]\displaystyle\mathsf{\overline{KV}}[/tex], which are intersected by line [tex]\displaystyle\mathsf{\overline{KV}}[/tex]. The prompt requires us to determine the relationship between [tex]\displaystyle\mathsf{\overline{RT}}[/tex] and [tex]\displaystyle\mathsf{\overline{RS}}[/tex].
Definitions:Parallel lines are non-intersecting lines that are coplanar and have the same slope.
Perpendicular lines: the intersection between two lines that form right angles. Perpendicular lines also have negative reciprocal slopes.
Transversal : a line that intersects at least two distinct coplanar lines in at least two or more definite points.
Explanation:We will use the given diagram and the following theorems/postulates to prove the relationship between lines [tex]\displaystyle\mathsf{\overline{RT}}[/tex] and [tex]\displaystyle\mathsf{\overline{WS}}[/tex].
The Parallel Postulate states that given line [tex]\displaystyle\mathsf{\overline{WS}}[/tex] and a point that is [tex]\displaystyle\sf\doubleunderline{\underline{\underline{not}}}[/tex] on line [tex]\displaystyle\mathsf{\overline{WS}}[/tex] , then there is exactly one line through that point that is parallel to line [tex]\displaystyle\mathsf{\overline{WS}}[/tex]. The Perpendicular Postulate states that given line [tex]\displaystyle\mathsf{\overline{KV}}[/tex] and point R that is not on line [tex]\displaystyle\mathsf{\overline{KV}}[/tex], then there is a definite line through point R that is perpendicular to line [tex]\displaystyle\mathsf{\overline{KV}}[/tex]. The Perpendicular Transversal Theorem states that given a transversal, [tex]\displaystyle\mathsf{\overline{RT}}[/tex], which is perpendicular to one of the parallel lines, [tex]\displaystyle\mathsf{\overline{WS}}[/tex], then it means that transversal [tex]\displaystyle\mathsf{\overline{RT}}[/tex] is also perpendicular to the other parallel line, [tex]\displaystyle\mathsf{\overline{KV}}[/tex].Now that we have established the necessary postulates and theorem, we can state that:
If [tex]\displaystyle\mathsf{\overline{WS}}[/tex] ║ [tex]\displaystyle\mathsf{\overline{KV}}[/tex], (Parallel Postulate) and [tex]\displaystyle\mathsf{\overline{KV}}[/tex] ⊥ [tex]\displaystyle\mathsf{\overline{RT}}[/tex], (Perpendicular Transversal Theorem ), then [tex]\displaystyle\mathsf{\overline{RT}}[/tex] ⊥ [tex]\displaystyle\mathsf{\overline{WS}}[/tex] (Perpendicular Postulate). ________________________Keywords:

sorry would not let me copy and paste i need the answer to number 7
Step-by-step explanation:
well, what do we expect in theory ?
a coin has a 50/50 chance for beads or tails. so, a probability of 1/2 for either one.
the probability for a survival number in a die is 1/6.
remember, the probability is always desired results over total possible results.
so, the combination is a simple multiplication.
the probability to get a certain side of the coin AND a certain number on the die is
1/2 × 1/6 = 1/12
so, this is what we would expect in theory : every combination happens in 1/12 of all cases.
now, what do we see in our practical experiment ?
there were 24 events (so, the total possible results are 24).
how many of them had heads and a 3 (the desired results) ?
there was only 1 result (in fact, there was only one 3 independently from the coin result, which is surprisingly low for 24 rolls of a die).
so, our experiment shows us a ratio or experimental probability of
1/24
for the desired result of heads with a 3 on the die.
we expected to get a ratio of
1/12 = 2/24
so, in reality, we got 1/24 less than theoretically expected.
The rectangular floor of a classroom is 26 feet in length and 24 feet in width. A scale drawing of the floor has a length of 13 inches. What is the area, in square inches, of the floor in the scale drawing?
Step-by-step explanation:
The area of the floor of the scale drawing and the scale factor are 72 in² and 1/4 respectively
Actual Length = 36 feets
Actual width = 32 feets
Model width = 9 inches
The scale factor = 9 / 36 = 1/4
The length of the model canbe calculated thus :
Actual Length × scale factor
Model width = 32 × 1/4 = 8 inches
The Area of a rectangle can be calculated using the relation :
Area = Length × width
Area of floor = 8 inches × 9 inches = 72 inch²
Therefore, the area of the floor of the scale drawing is 72 in²

The area of the rectangular floor in the scale drawing is A = 156 inches²
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the rectangular floor in the scale drawing be A
Let the length of the rectangular floor be L = 26 feet
Now , the length of the rectangular floor in scale drawing = 13 inches = L/2
And , the width of the rectangular floor be W = 24 feet
So , the width of the rectangular floor in scale drawing = W/2 = 12 inches
Now , Area of Rectangle = Length x Width
Substituting the values in the equation , we get
The area of the rectangular floor in the scale drawing A = 13 x 12
The area of the rectangular floor in the scale drawing A = 156 inches²
Hence , the area of rectangle is 156 inches²

O yes, using pythagorean theorem, both sides of the equation equal 136
O No, using the pythagorean theorem, both sides of the equation are not equal
Answer:
D
Step-by-step explanation:
Remark
The two legs when each of them is squared = 136 by
6^2 + 10^2 = 36 + 100 = 136
The hypotenuse is 12
12^2 = 144
The answer is that it is not a right angle triangle having 2 legs and a hypotenuse. That is because both sides are not equal.
