Sometimes the relationships involving secants, tangents, and chords can be difficult to remember. There is basically one rule that applies to all of these geometries:
the product of segment lengths to the circle from the point of intersection of the secants/tangents/chords is the same
A tangent can be thought of as a secant that has a length of 0 between its end points. That is, the two lengths from the point of intersection to the circle are the same.
Here is an example of this rule applied to chords:

Find the value of X for the image below
Geometry
Answers
Answer:
x = 8
Step-by-step explanation:
The value of x can be found by equating the associated angle with its vertical angle. That vertical angle is the difference between the one marked 18° and the right angle.
∠ZJW = ∠HJZ -∠WJZ = 90° -18° = 72°
∠GJL ≅ ∠ZJW
(9x)° = 72°
x = 72/9 = 8

Answer:
rule: y = 2x -6n = 22Step-by-step explanation:
We can look at the ratios of differences between x and y values to determine the nature of the sequence.
x-differences
9 -8 = 1; 11 -9 = 2;
y-differences
12 -10 = 2; 16 -12 = 4;
__
The ratios Δy/Δx are 2/1 = 2 and 4/2 = 2. That is, the points lie on a straight line with slope Δy/Δx = 2.
The y-intercept of the line can be found using the formula ...
b = y -mx
b = 10 -2(8) = -6 . . . . for (x, y) = (8, 10)
So, the rule relating x and y is ...
y = 2x -6

What is the value of x?
Answers
Answer:
x = 5
Step-by-step explanation:
Vertical angles are congruent, so ...
∠E = ∠F
8x +8 = 2x +38
6x = 30 . . . . . . . . . subtract (2x+8)
x = 5 . . . . . . . . . . . divide by 6
Answer:
Since ZE and ZF are vertical angles, they are congruent.
8x+8 = 2x+38
8 = 2x-8x+38
8 = -6x+38
8-38 = -6x
-30 = -6x
x = -30/-6

Find the LCD for 5/m2+9m+20, 3m/m2+11m+28
Answers
Answer:
The LCD of the two given fraction is (x + 4)(x + 5)(x + 7)
Step-by-step explanation:
In the algebraic fractions, the LCD is the least common denominator to find it do that:
Factorize each denominatorTake all the factors without repeating factorsLet us do that with our question
∵ The denominator of the first fraction is m² + 9m + 20
→ Factorize it into two factors
∵ 20 = 4 × 5 ⇒ the last term
∵ 4 + 5 = 9 ⇒ the coefficient of the middle term
∴ m² + 9m + 20 = (x + 4)(x = 5)
∴ The factors of m² + 9m + 20 are (x + 4) and (x + 5)
Do the same with the 2nd denominator
∵ The denominator of the second fraction is m² + 11m + 28
→ Factorize it into two factors
∵ 28 = 4 × 7 ⇒ the last term
∵ 4 + 7 = 11 ⇒ the coefficient of the middle term
∴ m² + 11m + 28 = (x + 4)(x + 7)
∴ The factors of m² + 11m + 28 are (x + 4) and (x + 7)
∵ The factors of the two denominators are (x + 4), (x + 5), (x + 4), (x + 7)
→ LCD will be all factors without repeating which means we will
take the factor (x + 4) just one time, we will not repeat it.
∴ LCD = (x + 4)(x + 5)(x + 7)
∴ The LCD of the two given fraction is (x + 4)(x + 5)(x + 7)

Find the area bounded by the curves x = 2y2 and x = 1 – y. Your work must include an integral in one variable.
Answers
Answer:
y^2 = 2x + 6
2x = y^2 - 6
x = 1/2(y^2 - 6)
The points of intersection of the curves are calculated:
y + 1 = 1/2( y^2 - 6)
2y + 2 = y^2 - 6
y^2 - 2y - 8 = 0
( y - 4)(y + 2) = 0
y = 4, -2
when y = 4, x = 5 and when y = -2 x = -1.
Integrating between y = 4 and y = -2

suppose f(x)=2x-5,g(x)=-3-1,and h(x) =2x2+x-7 calculate f(-7)
Answers
Answer:
f(-7) = -19
Step-by-step explanation:
Let us solve the problem
∵ f(x) = 2x - 5
∵ g(x) = -3x - 1
∵ h(x) = 2x² + x - 7
→ We need to find f(-7), that means substitute x in f(x) by -7
∵ x in f(x) = -7
∵ f(x) = 2x - 5
∴ f(-7) = 2(-7) - 5
→ Calculate 2 × (-7)
∴ f(-7) = -14 - 5
→ Add them
∴ f(-7) = -19

A radio station gave away 184 tickets to a concert. They gave away 3 times as many tickets to listeners as to employees. How many tickets did they give away to employees?
A.
92 tickets
B.
138 tickets
C.
74 tickets
D.
46 tickets
Answers
Answer:
D
Step-by-step explanation:
total=184 tickets
listeners= x tickets
employees=y tickets
184=x+y
x=3y
plug x into the first equation.
184=3y+y
184=4y
184/4=46
y=46
now plug y into the second equation
x=3(46)
x=138
the listeners got 138 tickets, and the employees got 46 tickets.
An event organiser is filling some party bags for a children's party. Each bag contains sweets, stickers and crayons. 40% of the items are stickers. The ratio of sweets to crayons is 5:3 The event organiser uses 150 sweets in total. She fills 10 party bags. How many stickers does she put in each bag?
Answers
Answer: 16 stickers
Step-by-step explanation:
The ratio of sweets to crayons is 5:3
we know she is using 150 sweets.
so if 5 = 150, then 3 = 90.
We know there are 90 crayons and 150 sweets.
So there are a total of 240 non-sticker items
If 60% = 240, then 40% = 160
Now we know that there are 150 sweets, 90 crayons, and 160 stickers.
If she is filling 10 bags, then there are 15 sweets, 9 crayons, and 16 stickers in each.
So there are 16 stickers/bag.
