JL is a common tangent to circles M and K at point J. If angle MLK measures
619, what is the length of radius MJ? Round to the nearest hundredth. (Hint:
Show that triangles LMJ and LKJ are right triangles, and then use right triangle
trigonometry to solving for missing sides of the right triangles.) (10 points)
pls help
Answer:
MJ = 6.5
Step-by-step explanation:
Tangent lines to a circle are perpendicular to the radius.
tan 68° = JL/3
2.4751 = JL/3
JL = 7.4253
∠JLK = 90° - 68° = 22°
∠MLJ = 61° - 22° = 39°
sin 61° = MJ/7.4253
MJ = 7.4253(0.8746) = 6.5
The length of radius MJ is 5.99 units
How to calculate the radius MJ?Start by calculating the length JL using the following tangent ratio
tan(68°) = JL/3
Make JL the subject
JL = 3 * tan(68°)
Evaluate the product
JL = 7.4
From the figure, the measure of angle MLJ is:
∠MLJ = MLK - JLK
Where:
∠JLK = 90° - 68° = 22°
So, we have:
∠MLJ = 61 - 22
∠MLJ = 39
The radius MJ is then calculated using the following tangent ratio
tan(39) = MJ/JL
This gives
tan(39) = MJ/7.4
Make MJ the subject
MJ = 7.4 * tan(39)
Evaluate
MJ = 5.99
Hence, the length of radius MJ is 5.99 units

Answer:
Below in bold.
Step-by-step explanation:
C1 = 180 - C2
= 180 - (170-2x)
= 10 + 2x
So B3 = 10+2x (alternate angles).
and B2 = 90 - B3
= 90 - (10 + 2x)
= 80 - 2x.
What are the solution(s) of -1/2X+4= X+ 1?
O-1 and 8
О 1 and 4
O 2
O 3
Answer:
X = 2
Step-by-step explanation:
-1/2X+4= X+ 1
Add 1/2X to each side
-1/2X+ 1/2 X+4= X+ 1 + 1/2 X
4 = 3/2 X +1
Subtract 1 from each side
4-1 = 3/2 X +1-1
3 = 3/2 X
Multiply each side by 2/3 to isolate x
3 * 2/3 = 3/2 X * 2/3
2 =X

a. The third side must be greater than 7 inches
b. The third side must be equal to or greater than 7 inches
c. The third side must be less than 7 inches
d. The third side must be less than or equal to 7 inches
Answer:
In a triangle the sum of any two sides must be greater than the third side. We have 3+4=7 which is less than 8. So this triangle is never true.

Number of 8-ounce Glasses
Based on this histogram, which statement must be true?
A On exactly 2 of these days, Shane drank 1 to 2 glasses of water.
BOn exactly 3 of these days, Shane drank 7 to 8 glasses of water,
C On exactly 25% of these days, Shane drank 3 to 4 glasses of water.
Don exactly 60% of these days, Shane drank 5 to 6 glasses of water
The histogram representing the data is attcwhwd in the picture below.
Answer:
C On exactly 25% of these days, Shane drank 3 to 4 glasses of water.
Step-by-step explanation:
The number of 8 - ounce glasses is represented on the x - axis and the number of days on the y - axis.
From the histogram ;
Shane drank 1 - 2 glasses on exactly 1 day
Shane drank 3 - 4 glasses on exactly 3 days
Shane drank 5 - 6 glasses on exactly 6 day
Total number of days = 12
60% of 12 = 7.2
On exactly 60% of the days, which is 7.2 days, number of glasses drunk isn't covered by the histogram
25% of 12 ; 0.25 * 12 = 3 days
From the histogram, number of glasses consumed is 3 - 4 glasses ; which is the only true statement about the histogram in the options given.

Which of these lengths CANNOT represent the sides of a triangle? {28, 30, 58} {32, 34, 60} {13, 20, 27} {2, 4, 5}
Answer:
[tex]A.\ {28, 30, 58}[/tex]
Step-by-step explanation:
Required
Which of the lengths do not form a triangle
To do this, we make use of triangle inequality theorem which states that.
[tex]a + b > c[/tex]
[tex]b + c > a[/tex]
[tex]a + c > b[/tex]
Where [tex]a,\ b\ and\ c[/tex] are the sides of the triangle.
So, we have:
[tex]A.\ {28, 30, 58}[/tex]
[tex]28 + 30 > 58[/tex] --- False
[tex]58 + 30 > 28[/tex] --- True
[tex]28 + 58 > 30[/tex] --- True
[tex]B.\ {32, 34, 60}[/tex]
[tex]32 + 34 > 60[/tex] -- True
[tex]32 + 60 > 34[/tex] -- True
[tex]34 + 60 > 32[/tex] -- True
[tex]C.\ {13, 20, 27}[/tex]
[tex]13 + 20 > 27[/tex] -- True
[tex]13 + 27 > 20[/tex] -- True
[tex]20 + 27 > 13[/tex] --- True
[tex]D.\ {2, 4, 5}[/tex]
[tex]2 + 4 > 5[/tex] --- True
[tex]2 + 5 > 4[/tex] -- True
[tex]5 + 4 > 2[/tex] --- True
From the computations above, only (A) cannot form a triangle
<1 and <2 are complementary angles.the measure of <1 is 10
the Measure of <2 is 4c
Answer:
c = 20
Step-by-step explanation:
You have not really asked a question.
I will assume you are asking about the value of c.
The measure of angle 1 is 10 (assuming degrees!), so the measure of angle 2 is 80. (Complementary angles have measures that sum to 90.)
The measure of angle 2 is also described as 4c, so 4c = 80. That makes c = 20.

EMERGENCY PLS HELP: Calculate the volume.
Answer:
[tex]525\pi[/tex]
Step-by-step explanation:
Volume of a cylinder is given by the function [tex]v=\pi r^{2}h[/tex]
where v is volume, r is radius and h is height.
In order to find the radius we just divide the diameter in half and get
[tex]\frac{10}{2} =5=r[/tex]
now we just plug the values in the formula
[tex]v=\pi r^{2}h\\=\pi (5^{2})(21)\\=\pi (25)(21)\\=525\pi[/tex]
Answer:
Volume of a cylinder: V = π (r^2) h
Step-by-step explanation:
First, find your radius and your height.
H = 21
D = 10
R = 1/2 d = 5
Then plug them into the equation: V = π (r^2) h
V = π (5^2) 21
V = π (25) 21
V = π (25 x 21)
V = π (525)
V = 525π

The boiling temperature (in degrees Celsius) of platinum is 199 more than four times the boiling temperature $z$ (in degrees Celsius) of zinc.
a. Write an expression that represents the boiling temperature (in degrees Celsius) of platinum.
b. The boiling temperature of zinc is 907 degrees Celsius. What is the boiling temperature of platinum?
Answer: THIS IS SO HARD!
Step-by-step explanation:
The required boiling temperature of platinum is 3,739 degrees Celsius.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Here,
a. Let's start by defining a variable for the boiling temperature of zinc, which we'll call z.
According to the problem statement, the boiling temperature of platinum is 199 more than four times the boiling temperature of zinc. In other words,
Boiling temperature of platinum = 4z + 199
So the expression that represents the boiling temperature of platinum in degrees Celsius is:
4z+199
b. The problem tells us that the boiling temperature of zinc is 907 degrees Celsius. So we can substitute this value for z in our expression:
4z+199 = 4(907)+199 = 3,739
Therefore, the boiling temperature of platinum is 3,739 degrees Celsius.

Step-by-step explanation:
The volume of the box is ...
V = LWH
V = (3 in)(4 in)(6 in) = 72 in³
__
65% of the box is filled with a toy, so the remaining 100% -65% = 35% is filled with packing beads. The volume of packing beads required is ...
0.35 × 72 in³ = 25.2 in³
25.2 in³ of foam packing beads are used to fill each box.
