One interior angle of a triangle is 60⁰. The other angle measures are 25⁰ and x⁰. Which of the following could be the values of x?

Answer:

1.37

Step-by-step explanation:

I just used my calculator lol

Answer:

Since this triangle seems to be 180 degree, and one angle is 90 degrees and the other is half thslat value (45), the other value will be 45 degrees. It is an Isosceles triangle

Answer:

Line of reflection → x = 1

Step-by-step explanation:

Coordinates of B → (3, 2)

Coordinates of B' → (-1, 2)

If point B is reflected across a vertical line x = a, both the points B and B' will be equidistant from the line of reflection.

Coordinates of the midpoint of the segment joining B and B'

= [tex](\frac{x_+x_2}{2},\frac{y_1+y_2}{2})[/tex]

= [tex](\frac{3-1}{2},\frac{2+2}{2})[/tex]

= (1, 2)

Line of reflection will pass through this midpoint (1, 2)

Therefore, equation of the line of reflection will be,

x = 1

Answer:

x=13

Step-by-step explanation:

Since both angles are vertical angles and are therefore congruent, the expression is equal to 114.

7x+23=114

Subtract 23 from both sides.

7x=91

Divide both sides by 7.

x=13

D) y = 12

Step-by-step explanation:

One can use the angle bisector theorem to solve this problem. The angle bisector theorem states:

[tex]\frac{a_1}{b}=\frac{a_2}{c}[/tex]

Where ([tex]a_1[/tex]) and ([tex]a_2[/tex]) are a part of the side that is intersected by the angle bisector and ([tex]b[/tex]) and ([tex]c[/tex]) are the other two sides in the triangle. Substitute in the given values and solve for the unknown.

[tex]\frac{4}{8}=\frac{6}{y}[/tex]

Simplify,

[tex]\frac{1}{2}=\frac{6}{y}[/tex]

Answer:

a-1.- location 1: =0.01- location 2: =0.113

a-2. F= 0.08849

b.  A. yes.

c.  t= -1.020

d. B. No.

Step-by-step explanation:

Location1(%C)             Location2(%C)

      x                  x²                      y                     y²

1   10.40           108.16                  10.10          102.01

2  10.20           104.04                  10.90         118.81

3  10.30           106.09                 10.20          104.04

4  10.40            108.16                  10.70         114.49

5  10.20            104.04                  10.40       108.16        

∑   51.5              530.49                  52.3         547.51      

x`= ∑x/n1 = 51.5/5= 10.3;    y`= ∑y/n2= 52.3/5= 10.46

Sx² = 1/n1-1[ ∑x² - (∑x)²/n1] = 1/4[  530.49 - (51.5)²/5]

        = 1/4[ 530.49 - 530.45] = 0.01

Sy² = 1/n2-1[ ∑y² - (∑y)²/n2] = 1/4[  547.51 - (52.3)²/5]

        = 1/4[ 547.51 - 547.058] = 0.113

F= Sx²/Sy²= 0.01/0.113= 0.08849

The critical region is F ≥ F(0.025) (5,5)= 7.15

and  F ≤ 1/F(0.025) (5,5) = 1/7.15= 0.13986

Since the calculated value of F =0.08849 falls in the critical region we conclude that  the two standard deviations for the locations significantly different at the 95% confidence level.

c.   t= x1`-x2`/ sqrt ( s₁²/n₁ + s₂²/n₂)

t= 10.3-10.46/ sqrt( 0.01/5 +0.113/5)

t=- 0.16/0.15684

t= -1.020

d.  The calculated value t= -1.020   does not fall in the the critical region

t (0.025) (4) = ±2.776  we conclude that the  means for the two different locations are not significantly different at the 95% confidence level.

Answer:

5 X 4

Step-by-step explanation:

If you plot the dots, youll obviously see a rectangle. The height of the rect. is 4, while the length is 5, so the measurements would be 5 x 4.

Approximate Answers:

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

Explanation:

Your diagram is 100% correct. Nice work.

To get the area of the trapezoid, we could use the area of a trapezoid formula below:

A = h*(b1+b2)/2

In this case, we have,

the bases are parallel to each other. The height is always perpendicular to the base. We won't use the "14" at all.

So,

A = h*(b1+b2)/2

A = 7*sqrt(3)*(18+25)/2

A = 7*sqrt(3)*21.5

A = (7*21.5)*sqrt(3)

A = 150.5*sqrt(3)

This is the exact area.

The approximate area is roughly

150.5*sqrt(3) = 260.673646539

The units for the area are in square km, or km^2. Though your teacher said for you not to include the units.

Another way to get the area of the trapezoid is to break the diagram into a rectangle and triangle as you have done so, and then find the area of each sub-piece. Adding the two smaller areas should lead to the result shown above.

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

To get the perimeter, we add up all of the exterior sides. We do not include the right-most vertical line that is 7*sqrt(3) km long because it is inside the figure. The horizontal segment that is 7 km long is part of the "25 km" segment, so we'll ignore that 7.

Adding the four exterior sides leads to:

7*sqrt(3)+18+14+25 = 57+7*sqrt(3)

This value is exact. It approximates to

57+7*sqrt(3) = 69.12435565

The units for the perimeter are in kilometers, and you won't have any exponent over the "km". While your teacher doesn't want the units, it's still handy to know what the units would be.

Step-by-step explanation:

solution given:

for rectangle

length [l]=18km

breadth [b]=7√3 km

for triangle

base[b1]=25-18=7km

height [h]=b=7√3km

for area :area of. (rectangle +triangle}=

l×b+1/2 b1×h=18×7√3+1/2 ×7×7√3=260.67km²

now

perimeter=sum of all sides

=18+14+25+7√3=69.12km

Step-by-step explanation:

I just took the USATESTPREP quiz and that is the answer.

 Option (C) will define the changes in the graph of the function with the values of 'd'.

 Given function in the question → y = alog(x + c) + d

Rules for the translation of a function,

 Hence, in the given function y = alog(x + c) + d, positive value of 'd' will define the shifting of the parent function upwards.

And for the negative value of 'd' will define the shift of the function downwards.

     Option (C) will be the correct option.

Answer:

In naming a ray, we always begin with the letter of the endpoint (where the ray starts) followed by another point on the ray in the direction it travels. Since the vertex of the angle is the endpoint of each ray and our vertex is , each of our rays must begin with . Only fails to do so.

Answer:

A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).

Answer:

Step-by-step explanation:

This is not a function.

A function has to have 1 y associated with each x. This relationship has 2 except for 1 point (the vertex at 3,0).

You can write a domain and range for it.

The domain is

- infinity < x < 3

The range is

-infinity  < x < + infinity.

Answer:

If Angle 1 is 110,

then the second angle to complete the straight angle (180 degrees) is...

180 - 110 = 70

Angle 2 = 110 (same as Angle 1, plus it's obtuse)

Angle 3 = 70 (it's acute)

Angle 4 = 70 (same as Angle3, plus it's acute)

Step-by-step explanation:
