In the illustration above, a circle with a few lines intersecting at various locations is shown. So, if we split the circle in half, the resulting semicircle has a vertical angle of 180 degrees. Since ∠ROP = 125°, ∠POS = 55° is obtained by taking 180° away from 125°. ∠POS and ∠QOR are equivalent terms. Also, ∠ROP = ∠QOS.
What is lines intersecting?
In a plane, intersecting lines are any two or more lines that cross one another. The point of intersection, which can be found on all intersecting lines, is where the crossing lines share a common point.
the characteristics of intersecting lines
The intersecting lines (two or more) never cross over at more than one location.
Any angle may be used to intersect the lines in any direction. Always larger than 0° and less than 180°, this angle is generated.
A pair of vertical angles are created by two intersecting lines. The vertical angles have the same vertex and are opposing angles (which is the point of intersection).

Wally and drake both wanted to see the moons of jupiter. they each wanted to buy a telescope that sold for $62.48. together they had a total of $95. how much more money did they have left to save?
The amount of money Wally and Drake have left to save is equal to $29.96 if each one of them wanted to buy a telescope.
The amount of money left to be saved can be calculated by using an algebraic expression.
First, we determine the cost of two telescopes if each one of them wanted to buy a telescope to see the moons of Jupiter.
As the cost of one telescope is $62.48, the cost of two telescopes will be;
62.48 + 62.48 = 124.96
An algebraic expression can be given as;
95 + x = 124.96
where x is the money left to be saved.
Solving for x;
x = 124.96 - 95
x = 29.96
Hence, $29.96 is the amount left to be saved for each one of them to buy a microscope.

The coordinates of the endpoints of line segment se are s(-7,3) and e(2,-6). if point m is on se, what are the coordinates of m such that sm:me is 1:2?
By applying the section formula between three points A, C and B we find that the coordinate of m is ( -4, 0)
Let's suppose we have a line on which we have 3 linear dots A, C, and B respectively, in this we have to use the section formula,
Where A = x1, y1
B = x2, y2
C = m:n
According to the section formula
C = (mx2 = nx1) / m+n * (my2 + ny1) / m+n
Sm/ Me = 1/2
Using section formula :
the coordinates of m = (2-14)/1+2 , (-6+6) / 1+2
the coordinates of m = ( -12/3 , 0/3)
the coordinates of m = ( - 4 , 0 )

The sequence that contains all the given terms is:

Then the correct option is C.
Which sequence can be used to find the n-th term?
Here we have the elements:
a₃ = 0
a₄ = 6
a₅ = 12
a₆ = 18
a₇ = 24
So each term adds 6 to the previous one, so trivially the relation is of the form:
aₙ = aₙ₋₁ + 6
Now we need to find the first term.
We can rewrite the above equation as:
aₙ₋₁ = aₙ - 6
Then we willget:
a₂ = a₃ - 6 = 0 - 6 = -6
a₁ = a₂ - 6 = -6 - 6 = -12

What is meant by the term inequality?In mathematics, an inequality is a connection between two expressions and values that aren't equal to each other.
Rule 1: Once inequalities are linked, they can be crossed. As a result, if an is greater than b and b is higher than c, a will be greater than c as well.Rule 2: When you swap the values, this same sign also flips.Rule 3: An inequality could be either > or, but not both at the same time.As per the given question;
The total budget of Salma is $75.
The flat cost is $55.
The cost per gigabytes is $5.
Let the number of gigabytes used be 'x'.
Then, the inequality becomes.
55 + 5x < 75
Subtracting 55 from both sides.
55 + 5x - 55 < 75 - 55
5x < 20
Divide both sides by the 5

Angles of ∠y is 45° and ∠x is 135°.
What are angles?An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
Given Data
SRQ = 130°
∠R = 130°
As PR is the same line
So. angles of the line is 180°.
∠Y + ∠R = 180
∠y = 180 - 135
∠y = 45°
Now, PQ is the straight line
∠y +∠x = 180

What does probability mean in math?Probability is a way to gauge how likely something is to happen. Many things are hard to predict with complete certainty. We can only forecast how likely an event is to occur using it, or how likely it is to occur.
The probability is typically defined as the proportion of positive outcomes to all outcomes in the sample space. Probability of an event P(E) = (Number of favourable outcomes) is how it is stated (Sample space).
based on the facts provided;
p(0) = p(w,w)

p(1) = p(t, w+t) + p(w, t)
= 2p(w,t) +p(t,t) = 2·.29·.37 + .37² = 0.3515
p(2) = p(f, w+t+f) +p(w+t, f)

two gears, A and B. are arranged so that the teeth of one gear is mesh with the teeth of another. Gear A turns clockwise and has 54 teeth. Gear B turns counterclockwise and has 36 teeth. If gear A makes 5.5 rotations, how many turns will gear B make?
The number of turns gear B will make is 8.25 turns
How to find the number of turns gear B will makeGiven data
Gear A turns clockwise and has 54 teeth
Gear B turns counterclockwise and has 36 teeth
gear A makes 5.5 rotations
One of the gears is driving the other hence the distance covered by each of the gears is constant.
The distance is the product of the number of rotations and the number of teeth and this should be a constant
Therefore, let the number of rotations of gear B be x
54 teeth * 5.5 rotations = 36 teeth * x rotations
x rotations = ( 54 teeth * 5.5 rotations ) / 36 teeth
x rotations = 54/36 * 5.5
x rotations = 1.5 * 5.5
x rotations = 8.25
We can therefore say that gear B will make 8.25 rotations

What are coordinates?A pair of numbers that use the horizontal and vertical separations from the two reference axes to describe a point's location on a coordinate plane. Typically represented by the x-value and y-value pair (x,y).So, a point (x, y) becomes (-y, x) if it is rotated 90° anticlockwise with respect to the origin.
Since, N = (-7, -3) ⇒ N' = (3, -7)O = (-5, 4) ⇒ O' = (-4,-5)W = (-2, 1) ⇒ W' = (-1, -1)(Refer to the image attached below)
