"La suma de la medida de los ángulos interiores de cualquier triángulo, es igual a dos triángulos rectos, o sea a 180°."

Answers

Answer:

Efectivamente, la suma de la medida de los ángulos internos de cualquier figura triangular es igual a 180º. Ahora bien, la oración posee un error de redacción, pues tanto los triángulos rectos como los equiláteros o los isósceles poseen dicha característica, es decir, no es únicamente una característica de los triángulos rectos. Además, la suma de los ángulos interiores de dos triángulos rectos sería igual a 360º, no a 180º.  

If the measure of arc AD is 65 degrees and the measure of arc BC is 45 degrees, what is the measure of angle BEC?

Answers

Answer:

[tex]\angle BEC=55 \textdegree)[/tex]

Step-by-step explanation:

From the question we are told that:

Arc [tex]AD =65 \textdegree[/tex]

Arc [tex]BC =45 \textdegree[/tex]

Given The angle of intersecting chords theorem

Generally the equation for angle BEC is mathematically given by

 [tex]\angle BEC=\frac{1}{2} (\angle of arc AD+\angle of arc BC)[/tex]

 [tex]\angle BEC=\frac{1}{2} (65 \textdegree+45 \textdegree)[/tex]

 [tex]\angle BEC=55 \textdegree)[/tex]

X^2-3x=7/4
Solve by completing the square

Answers

Answer:

Step-by-step explanation:

X^2-3x=7/4 should first be rewritten in standard form, which here would be:

x^2 - 3x - 7/4 = 0.

1.  Identify the coefficient of the x term and take half of that number:

    -3/2

2. square this result:  (-3/2)^2 = 9/4

3.  add this last result, 9/4, between the -3x term and the -7/4 term, and then      subtract it as shown:

     x^2 - 3x + 9/4 - 9/4 - 7/4 = 0

4.  Rewriting the first 3 terms as the square of a binomial, we get:

    (x - 3/2)^2  -  16/4 = 0, or    (x - 3/2)^2  =  16/4

5.  Take the square root of both sides, obtaining:

     x - 3/2 = ±√4/2 or ±√2

6.  Write out the two roots:  x = 3/2 + √2

     and                                   x = 3/2 - √2

Find the exact values of csc and sec

Answers

Answer:

cosec theta = 5/4

sec theta = 5/3

Step-by-step explanation:

Given that;

cot θ = 3/4

1/tanθ = 3/4

tanθ = 4/3

since tanθ = opp/adj

opp = 4

adj = 3

hyp^2 = 4^2 + 3^2

hyp^2 = 16+9

hyp^2 = 25

hyp = √25

hyp = 5

sin theta= opp/hyp

sin theta = 4/5

cosec theta = 1/sin theta

cosec theta = 1/(4/5)

cosec theta = 5/4

Get sec theta;

sec theta = 1/costheta

sec theta = 1/(3/5)

sec theta = 5/3

State if the two triangles are congruent. If they are, state how you know
A) SSS
C) ASA
B) Not congruent
D) SAS

Answers

Answer:

C) ASA

Step-by-step explanation:

angles are indicated equal and they share the common diagonal between those angles, so ASA

The given two triangles are congruent due to the ASA postulate, which is the correct answer that would be an option (C).

What are congruent triangles?

Two triangles are said to be congruent if their corresponding sides and angles are equal.

The given triangles are given in the figure.

We can see that there are two angles that are the same and one side is the same.

According to ASA, two triangles are congruent if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle.

So, we conclude that the given two triangles are congruent.

Hence, the given two triangles are congruent due to the ASA postulate.

Henri buys 126 inches of a fabric that costs $12 for each yard. How much dos Henri pay for the fabric

Answers

Answer: $47.28

Step-by-step explanation:

There are 126 inches of fabric.

You need to convert this to yard as that is the pricing unit.

1 yard = 36 inches

126 inches is:

Using the graph below, calculate the average rate of change for f(x) from
x = 0 to x =2

1) -4

2) -2

3) 2

4) 4

Answers

Answer:

4

Step-by-step explanation:

Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]

Where,

a = 0,

f(a) = f(0) = -2 (from the graph given)

b = 2,

f(b) = f(2) = 5 (from the graph)

Plug in the values

Average rate of change = [tex] \frac{5 - (-2)}{2 - 0} [/tex]

In circle J with m \angle HJK= 50m∠HJK=50 and HJ=16HJ=16 units, find the length of arc HK. Round to the nearest hundredth.

Answers

Answer:

13.96

Step-by-step explanation:

length of an arc = theta/360 * 2πr

Given

m<HJK = 50

HJ = 16units

Required

length of arc HK

arc HK = 50/360 * 2(3.14)(16)

arc HK = 5/36 * 100.48

arc HK = 502.4/36

arcHK = 13.96

hence the length of arcHK to nearest hundredth is 13.96

ANSWER I WILL GIVE U BRIANLIEST!!!

Answers

Answer:

9

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 9 when x = - 3

9 = - 3k ( divide both sides by - 3 )

- 3 = k

y = - 3x ← equation of variation

When y = - 27 , then

- 27 = - 3x ( divide both sides by - 3 )

9 = x

Every two out of three kids sang at the talent show. What percent of the kids did not sing at the talent show? (round)

Answers

66.7 %
convert to decimal the multiply by 100

33.3% do not sing in the talent show.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total number of kids = 3

Number of kids who sang = 2

The number of kids who do not sing.

= 3 - 2

= 1

The percentage of kids who do not sing.

= 1/3 x 100

= 33.33%

Thus,

33.3% do not sing in the talent show.
