Given:
A figure of a circle and two secants on the circle from the outside of the circle.
To find:
The measure of angle KLM.
Solution:
According to the intersecting secant theorem, if two secant of a circle intersect each other outside the circle, then the angle formed on the intersection is half of the difference between the intercepted arcs.
Using intersecting secant theorem, we get
[tex]\angle KLM=\dfrac{1}{2}(Arc(JON)-Arc(KM))[/tex]
[tex](3x-4)=\dfrac{1}{2}(271-(x+6))[/tex]
[tex](3x-4)=\dfrac{1}{2}(271-x-6)[/tex]
Multiply both sides by 2.
[tex]6x-8=265-x[/tex]
Isolate the variable x.
[tex]6x+x=265+8[/tex]
[tex]7x=273[/tex]
Divide both sides by 7.
[tex]x=\dfrac{273}{7}[/tex]
[tex]x=39[/tex]
Now,
[tex]\angle KLM=(3x-4)^\circ[/tex]
[tex]\angle KLM=(3(39)-4)^\circ[/tex]
[tex]\angle KLM=(117-4)^\circ[/tex]
[tex]\angle KLM=113^\circ[/tex]
Therefore, the measure of angle KLM is 113 degrees.

PLS HELP DUE AT MIDNIGHT
Answer:
m<BDC = 60 degrees
Step-by-step explanation:
m<EBD is 120, m<EBC = 180 (it's a straight angle) so m<DBC = 180-120= 60 degrees.
All angles in a triangle add up to 180. 60+60+x=180. 180-120=x=60.
Lines m and n are parallel. The measure of angle 6 is 55 114 57.6 3 What is the measure of angle 1? 1552
Answer:
125 degree
Step-by-step explanation:
As m // n, so angle 2 and angle 6 is the same so angle 2 = 55 degree, then angle 1 + angle 2 = 180 degree, so angle 1 = 180 - 55 = 125 degree.

5y- 3x = -1
Answer:
5y=4+3x, 5y-3x=-1
Step-by-step explanation:
To be parallel they must have different constants but the same slope.
5y-3x=-1
5y=-1+3x and 5y=4+3x fit these requirements.
The quantity of an element is decaying over time such that the amount of material
any time is given by the function F(t) = 6700(0.7)3t. Write an equivalent function
of the form F(t) = abt.
The equivalent function in the form y = ab^x is [tex]F(t)=2,298.1(0.7)^t[/tex]
Exponential functions:Give the exponential function in a general sense as y = ab^x
Given the exponential function [tex]F(t) = 6700(0.7)^{3t}[/tex]We are to write it in the form [tex]f(t) = ab^t[/tex]
This can be further expressed as;
[tex]F(t) = 6700(0.7)^{3t}\\F(t) = 6700(0.7^3)(0.7^t)\\F(t)=2,298.1(0.7)^t[/tex]
Hence the equivalent function in the form y = ab^x is [tex]F(t)=2,298.1(0.7)^t[/tex]

The straight line y = 3x +2 intersects the curve y = 2x^2 + 7x-11 at two points. Find the coordinates of these two points Give your answers correct to 2 decimal places.
Given:
The equation are
[tex]y=3x+2[/tex]
[tex]y=2x^2+7x-11[/tex]
To find:
The coordinates of intersection points.
Solution:
We have,
[tex]y=3x+2[/tex] ...(i)
[tex]y=2x^2+7x-11[/tex] ...(ii)
From (i) and (ii), we get
[tex]3x+2=2x^2+7x-11[/tex]
[tex]0=2x^2+7x-11-3x-2[/tex]
[tex]0=2x^2+4x-13[/tex]
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then by quadratic formula:
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
In the equation [tex]0=2x^2+4x-13[/tex], we have [tex]a=2,b=4,c=-13[/tex].
Using quadratic formula, we get
[tex]x=\dfrac{-4\pm \sqrt{4^2-4(2)(-13)}}{2(2)}[/tex]
[tex]x=\dfrac{-4\pm \sqrt{16+104}}{4}[/tex]
[tex]x=\dfrac{-4\pm \sqrt{120}}{4}[/tex]
Now,
[tex]x=\dfrac{-4+\sqrt{120}}{4}[/tex] and [tex]x=\dfrac{-4-\sqrt{120}}{4}[/tex]
[tex]x=1.7386[/tex] and [tex]x=-3.7386[/tex]
[tex]x\approx 1.74[/tex] and [tex]x\approx -3.74[/tex]
Putting x=1.74 in (i), we get
[tex]y=3(1.74)+2[/tex]
[tex]y=5.22+2[/tex]
[tex]y=7.22[/tex]
Putting x=-3.74 in (i), we get
[tex]y=3(-3.74)+2[/tex]
[tex]y=-11.22+2[/tex]
[tex]y=-9.22[/tex]
Therefore, the coordinates of the intersection points are (1.74, 7.22) and (-3.74,-9.22).

Anna makes a quilt by sewing together green, white, and yellow fabric. When she finishes, 2/6 of the quilt is green, and 3/6 is yellow. The rest is white. What fraction of the quilt is white? Show your work.
Answer:fraction of the quilt is white = 1/6
Step-by-step explanation:
Let the total quilt be = 1 ( since we are dealing with fraction)
The portion of quilt that is green 2/6
The portion of quilt that is yellow 3/6
The portion that is white = Total quilt −( portion of quilt that is green and yellow)
=1−( 2/6 + 3/6 )
=1 −5/6

Please help me find the value of x in the rectangle ABCD
Answer:
x = 52
Step-by-step explanation:
Hello there!
All of the angles in a rectangle are right angles
if a right angle has a measure of 90 degrees then we can find x by subtracting the given angle from 90
90 - 38 = 52 so we can conclude that x= 52
Step-by-step explanation:
Each angle in a quadrilateral is 90⁰ therefore 38⁰+x=90⁰
hence x=90⁰-38⁰ which gives you 52⁰
Lilo has 1,000 minutes per month on her cell phone plan. Write and solve an inequality showing the maximum number of minutes that Lilo can use it not be charge extra on her cell phone plan when she only used 615 minutes.
Answer:
Lilo has a maximum of 385 minutes to use on her cell phone.
A ≤ 385
Step-by-step explanation:
Let letter A represent the additional number of minutes that Lilo can talk
A + 615 ≤ 1,000
subtract 615 from both sides
A + 615 - 615 ≤ 1,000 - 615
A + 0 ≤ 385
A ≤ 385
Lilo has a maximum of 385 minutes to use on her cell phone.
A + 615 ≤ 1,000; A ≤ 385
