If two triangles have three congruent, corresponding angles, what additional information is needed to prove that the triangles are congruent?

Answer:

b) 94

Step-by-step explanation:

The Total Degree of a Triangle is 180 degrees. Knowing this, set up an equation.

68+26+x=180.

x is the complementary angle of the "?" angle.

Solve the equation.

94+x=180

x=86

Then Subtract 86 from 180 to find "?"

180-86=94

I hope this helps!

Answer:

94;b

Step-by-step explanation:

68+26=94. 180-94=86. 180-86=94.

Answer:

Age of the spear head = 6349 years.

Step-by-step explanation:

Expression to be used to calculate the age of the spear head,

[tex]N_t=N_0e^{-kt}[/tex]

Here, [tex]N_t[/tex] = Final amount of C-14

[tex]N_0[/tex] = Initial amount

[tex]k[/tex] = 0.0001

[tex]t[/tex] = Time in years

If [tex]N_t[/tex] = 53% of [tex]N_0[/tex] = [tex]N_0\times (0.53)[/tex]

[tex]0.53N_0=N_0e^{-0.0001\times t}[/tex]

[tex]0.53=e^{-0.0001t}[/tex]

[tex]\text{ln}(0.53)=\text{ln}(e^{-0.0001t})[/tex]

[tex]-0.634878=(-0.0001)t[/tex]

[tex]t=6348.78[/tex] years

[tex]t[/tex] ≈ [tex]6349[/tex] years

Therefore, age of the spear head = 6349 years.

Given:

The slope of a line is [tex]-\dfrac{3}{4}[/tex].

To find:

The lines in the options are parallel, perpendicular or neither parallel nor perpendicular to the given line.

Solution:

We know that the slopes of parallel lines are equal.

The slope of line Q and the slope of given line are same, i.e., [tex]-\dfrac{3}{4}[/tex]. So, the line Q is parallel to the given line.

The slope of a perpendicular line is the opposite reciprocal of the slope of the line because the product of slopes of two perpendicular lines is -1.

The slope of a line is [tex]-\dfrac{3}{4}[/tex]. It means the slope of the perpendicular line must be [tex]\dfrac{4}{3}[/tex]. So, the line N is perpendicular to the given line.

The slopes of line M and P are neither equal to the slope of the given line nor opposite reciprocal of the slope of the line.

Therefore, the lines M and P are neither parallel nor perpendicular.

Answer:

Rewrite the expression using the negative exponent rule   [text]{b}^{-n } = 1/bn

Step-by-step explanation:

1/y^3

Answer: 3

Step-by-step explanation: I don’t have an explanation but I got the same question on a quiz and 3 was the correct answer.

the possible values for y are in between 20 and 80 will be 3.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

If 12 is the greatest common factor of y and 36.

The value of y will be a multiple of 12 and greater than 36.

Then the numbers will be

12 x 4 = 48

12 x 5 = 60

12 x 6 = 72

Then the possible values for y are in between 20 and 80 will be 3.

They gave you the length of the two sides of the triangular part. Calculate the circumference of the semi circle on top.

Circumference of a semi circle is 1/2 x 2 x radius x PI

The radius is given as 3 ft.

Circumference  = 1/2 x 2 x 3 x 3.14 = 9.42ft

Perimeter is the length of the circumference of the semi circle plus the side lengths of the triangle:

The missing side is 53.6 units for the given right triangle.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

The right triangle is given in the question, as shown.

The ratio of the length of the side opposite the angle to the length of the hypotenuse of the triangle. The sine function is denoted by the symbol "sin" and is defined as follows:

sin(θ) = opposite / hypotenuse

Here, θ = 66°

Using the sine ratio in the given triangle, we get

sin 66° = perdenicular/hypertanuas

Substitute the known values in the above ratio,

sin 66° = 49/x

x = 49/sin 66°

x = 53.63717

Rounded to the nearest tenth,

x ≈ 53.6

Thus, the missing side is 53.6 units for the given right triangle.

Answer:

The distance between C and D is 4.2768 inches.

Step-by-step explanation:

As from A to B the distance is 5.625 inches and actual is 1688 miles

so,

1 mile = 5.625/1688 = 0.0033 inches

So, the distance between C and D is 1296 miles

= 1296 x 0.0033 inches = 4.2768 inches  

Answer:

$95.52

Step-by-step explanation:

Number of robots = 3

Cost of each robots = $398

Tax rate = 8%

Amount of tax of each robots = 8% of $398

= 8/100 × $398

= 0.08 × $398

= $31.84

TOTAL TAX to be paid = Amount of tax of each robots × Number of robots

= $31.84 × 3

= $95.52

TOTAL TAX to be paid = $95.52

Answer:

Charley's class.

Step-by-step explanation:

There are 25 students in Amanda class and 27 in Charley's.

Number of students with no pets in Amanda's = 7 which is 100 * 7/25 = 28%.

In Charley's class this is  8 which is 100 * 8/27 = 29.6%.

Answer:

Charley's class

Step-by-step explanation:

Amanda's class has 7 students with zero pets out of 25 total students. Charley's class has 8 students with zero pets out of 27 total students.

7/25 = 28% with zero pets

8/27 = around 30% with zero pets

Charley's class has a larger percentage of students with no pets

Let the tree equal x

100/220 = x / 176           Multiply both sides by 176

Answer:

[tex]79\%[/tex]

Step-by-step explanation:

The probability that the point is chosen in the circle is equal to the area of the circle divided by the area of the square.

Formulas used:

The segment marked as 1 represents not only the radius of the circle, but also half the side length of the square. Therefore, the side length of the square is 2, and we have:

Area of square: [tex]A=2^2=4[/tex]

Area of circle:

[tex]A=1^2\pi=\pi[/tex]

Therefore, the probability that the point will be inside the circle is:

[tex]\frac{\pi}{4}=0.78539816339\approx \boxed{79\%}[/tex]
