Given JM=27, Ml=16, Jl=46, Nk=15, KLM= 48, JkM=78, MJL=22, Find Each Missing Value.

Answers

Answer 1

Answer:

KL = 27

JK = 16

MK = 30

NL = 23

m∠JKL = 132°

m∠KLJ = 22°

m∠KMJ = 54°

m∠KJL = 26°

Step-by-step explanation:

The given parameters of the quadrilateral JKLM are;

JM = 27, ML = 16, JL = 46, NK = 15, KLM = 48, JKM = 78, MJL = 22

Taking the sides as parallel, we have that quadrilateral JKLM is a parallelogram

Therefore;

KL = JM = 27

JK = ML = 16

m∠KLJ = m∠MJL = 22°

MN = NK = 15

MK = MN + NK = 15 + 15 = 30

NL = JL/2 = 46/2 = 23

m∠KJM = m∠KLM = 48°

m∠KJL = m∠KLM - m∠MJL = 48° - 22° = 26°

m∠KML = m∠JKM = 78°

m∠MKL = 180° - m∠KML - m∠KLM = 180° - 78° - 48° = 54°

m∠MKL = 54°

m∠JKL = m∠JKM + m∠MKL = 78° + 54° = 132°

m∠KMJ = m∠MKL = 54°

Answer 2

Applying the properties of a parallelogram, the missing values are:

KL = 27; JK = 16; MK = 30; NL = 23

m∠JKL = 132°; m∠KLJ = 22°; m∠KMJ = 54°; m∠KJL = 26°

What are the Properties of a Parallelogram?Diagonals bisects each other into equal parts.Parallelograms have two pairs of opposite sides that are parallel and congruent to each other.Angles opposite each other in a parallelogram are equal.Consecutive angles in a parallelogram are supplementary.

Applying the properties of a parallelogram, we will find the given measures as follows:

KL = JM  (congruent sides)

KL = 27

JK = ML (congruent sides)

JK = 16

MK = 2(NK)

Substitute

MK = 2(15)

MK = 30

NL = 1/2(JL)

NL = 1/2(46)

NL = 23

m∠JKL = 180 - m∠KLM (supplementary angles)

m∠JKL = 180 - 48

m∠JKL = 132°

m∠KLJ = m∠MJL (congruent angles)

m∠KLJ = 22°

m∠KMJ = m∠MKL (congruent angles)

m∠MKL = 180° - 78° - 48° = 54°

m∠KMJ = m∠MKL = 54°

m∠KMJ = 54°

m∠KJL = 48° - 22°

m∠KJL = 26°

Answers

Answer:  D) 130

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

Explanation:

The three upper angles

AOBBOCCOD

all combine together to form a 180 degree straight angle. Let's add up the angle expressions and set the result equal to 180. That will help us solve for x.

(angle AOB) + (angle BOC) + (angle COD) = 180

(3x-28) + (90) + (66-x) = 180

2x+128 = 180

2x = 180-128 .... subtract 128 from both sides

2x = 52

x = 52/2 .... dividing both sides by 2

x = 26

Since x = 26, we can find the missing angles like so

angle AOB = 3x-28 = 3*26-28 = 50angle COD = 66-x = 66-26 = 40

Note how:

(angle AOB) + (angle BOC) + (angle COD) = 50+90+40 = 180

to help confirm we have the correct x value.

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

Afterward, we need to find angle BOD which is the combination of angles BOC and COD

angle BOD = (angle BOC) + (angle COD)

angle BOD = 90 + 40

angle BOD = 130

Angles BOD and AOE are vertical angles. It might help to erase ray OC so you can see the two vertical angles better. Vertical angles are always congruent, which means angle AOE is 130 degrees as well.

Step-by-step explanation:

So,A triangle is equal to 180 and you would add up the numbers you already have which equal 145.180-145= 35° and thats why the last letter would be 35° in your answer and be correct which would be that m<F=35° is the same as ABC in the last letter. Since,<B is the second letter in ABC and so is <E in DEF and have the same degree that would be the same as well so I hope that helps:)

Answer:

c

Step-by-step explanation:

the angles in a triangle have to add up to 180°

65 + 80 = 145

180-145 = 35

the missing angle is 35°

choice c matches because it has 2 of the same angle measures, which means they all have to be the same

1. A limited-edition soccer ball costs $30, and the
sales tax is 6%. What is the total cost?

Answers

Answer:

$31.80

Step-by-step explanation:

The ball will cost 100% of its price plus 6% of its price for a total of 106%.

To use percentages as a factor and multiply, they must be divide by 100, making the multiplication factor version of 106% 1.06.

Multiply the cost of the ball by your multiplication factor:

30 x 1.06 = 31.8

Money is written to two decimal places, making your answer $31.80

Answer:

$31.80

Step-by-step explanation:

First, find how much the sales tax is

$30 × 6%

Convert the percentage into a decimal

30 × 0.06

1.8

$1.80

Add the sales tax to the original cost

$30 + $1.80

$31.80
