Answers:

x = angle MLN = 35 degrees

angle FLJ = 55 degrees

=================================================

Explanation:

This problem is fairly tricky if you're not sure what to look for. A slight clue is that they've marked a red point that strangely doesn't have a label on it. It's a fairly small point but it's definitely there if you look closely. While this point's location isn't exactly what we want, we're fairly close. Start at point L and draw a ray through the center point P. Ray LP will intersect the circle at point A, as shown in the diagram below.

From here, draw segments FA and MA. Now notice that inscribed angle LMF = 55 and inscribed angle FAL both subtend the same arc. The term "subtend" basically means "cut off". This arc that the inscribed angles subtend is minor arc FL. A minor arc is where you travel the shorter path around the circle, which indicates its measure is less than 180 degrees.

Since inscribed angles LMF and FAL subtend the same minor arc, this makes the inscribed angles to be congruent.

In short: angle FAL is 55 degrees

----------------------

Segment LA goes through the center P. Through Thales theorem, we know that inscribed angle LFA is 90 degrees. Consequently, we can determine that inscribed angle FLA is 90-55 = 35 degrees.

Segment JL is tangent to the circle, meaning that angle ALJ is 90 degrees. So angle FLJ is 90-35 = 55 degrees.

It's not a coincidence that angle FLJ, angle FAL, and angle LMF are the same measure.

----------------------

We found that angle FAL was 55 degrees. Applying Thales theorem again shows that angle MAF is 90 degrees. Therefore, angle LAM is 90-55 = 35 degrees.

Focus now on triangle LMA. This is also a right triangle (Thales Theorem). The upper acute angle we found was angle LAM = 35, so the lower acute angle is ALM = 55.

Then we can find angle MLN = (angle ALN) - (angle ALM) = 90 - 55 = 35

In short, angle MLN = 35 degrees

Similar to the previous section, it is not a coincidence that angles LFM, LAM and MLN are the same measure.

------------------------

As an alternative, since we know angle FLJ = 55, and angle FLM is 90 degrees, this means...

(angle FLJ)+(angle FLM) + (angle MLN) = 180

55 + 90 + angle MLN = 180

145 + angle MLN = 180

angle MLN = 180 - 145

angle MLN = 35 degrees

Answer:

[tex]\angle NPM[/tex]

Step-by-step explanation:

Given

Circle of center P

Polygon JKLMN

Required

The central angle of JKLMN

From the question, we have that: the polygon and the circle have the same center (P).

This means that any central angle must pass through P

By this, PMN and NJK are incorrect

QPK divides the polygon and point Q is not on the vertex of the polygon.

By this, QPK is also incorrect

The final option NPM is correct, because P is at the center and points N and M are at the vertices of the polygon

Answer:

m<N=68

Step-by-step explanation:

opposite angles of the parallelogram are equal(or congruent):

4x+36=6x-2

6x-4x=36+2

2x=38

x=38/2=19

the sum of the angles of the parallelogram =360

4x+36=4(19)+36=112 angle P

6x-2=6(19)-2=112 angle M

let Q= N=x

2x+112+112=360

2x=360-224

2x=136

x=136/2=68

The radius will be half of your diameter so,

since 26 is your diameter half of that is = 13 is your new radius.

Now finding the area:

Answer:

16

Step-by-step explanation:

Draw a picture!

Length1 goes from (5, 2) to (10, 2)

since the y coordinate is the same

L1 = (10 - 5) = 5

Length2 goes from (5, 5) to (10, 5)

since the y coordinate is the same

L2 = (10 - 5) = 5

Width1 goes from (5, 2) to (5, 5)

since the x coordinate is the same

W1 = (5 - 2) = 3

Width2 goes from (10, 2) to (10, 5)

since the x coordinate is the same

W2 = (5 - 2) = 3

-----------------------

Perimeter

p = 5 + 5 + 3 + 3

p = 16

The perimeter of quadrilateral is 16 units.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilateral interior angle sums are always equal to 360 degrees.

Given coordinates,

(5,2), (10,2), (5,5), and (10,5)

let A, B, C, and D be the points of coordinates (5,2), (10,2), (5,5), and (10,5) respectively.

Length1 goes from (5, 2) to (10, 2)

since the y coordinate is the same

AB = (10 - 5) = 5

Length2 goes from (5, 5) to (10, 5)

since the y coordinate is the same

BC = (10 - 5) = 5

Width1 goes from (5, 2) to (5, 5)

since the x coordinate is the same

CD = (5 - 2) = 3

Width2 goes from (10, 2) to (10, 5)

since the x coordinate is the same

DA = (5 - 2) = 3

perimeter = sum of all sides

p = 5 + 5 + 3 + 3 = 16 units

Hence the perimeter is 16 units.

Answer:

300 : 450

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 = 5 parts

Divide 750 by 5 to find the value of one part of the ratio

750 ÷ 5 = 150 ← value of 1 part of the ratio , then

2 parts = 2 × 150 = 300

3 parts = 3 × 150 = 450

Then 750 in the ratio 2 : 3 = 300 : 450

The required answer is 750 in the ratio 2 : 3 = 300 : 450.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have to divide 750 into the ratio 2:3​

The ratio is given in the question

⇒ 2:3​

We can see that the sum of the parts of the given ratio as

⇒ 2 + 3 = 5 parts

Divide 750 by 5 to determine the value of one part of the ratio

So the value of 1st part of the ratio

⇒ 750 ÷ 5 = 150

Now, 2nd parts = 2 × 150 = 300

And, 3rd parts = 3 × 150 = 450

So, 750 in the ratio 2 : 3 = 300 : 450

Therefore, the required answer is 750 in the ratio 2 : 3 = 300 : 450.
