I think its 71, but I am not 100% sure. Take this as a secondary answer.
Answer:
C. 71°
Step-by-step explanation:
If angles 4 and 12 are equal and complementary, then they measure 45°
There is a triangle formed by angles 3, 11 and 12
the angle 3 = 64°, angle 12 = 45°
Then by the property of triangles:
angle 11 = (180 - 64 - 45)° = 71°

What is the best next step in the construction of the perpendicular bisector of AB?
Answers
Answer:
B
Step-by-step explanation:
Out of all the answers given as a choice B makes the most sense because the triangle AB and point of intersection of the two circles form an equilateral triangle.
In general to construct a perpendicular bisector after we drew the two circles we have to ...draw a straight line trough the points where the two circles intersect and that is our perpendicular bisector of AB.

Find the length of the missing side of the right triangle.
Answers
Answer:
39 units
Step-by-step explanation:Since two side lengths and a right angle are given, we can use pythogoras theorem to determine the missing side (c) of the triangle. It should be noted that pythgoras theorem can only be used if the triangle is a right triangle.
Pythogoras theorem formula:
[tex](\text{Side}_{1} })^{2} + (\text{Side}_{2} )^{2} = (\text{Hyptenuse})^{2}[/tex]
Substitute the legs of the triangle and the hyptenuse
[tex]\implies (36)^{2} + (15 )^{2} = (c)^{2}[/tex]
Simplify both sides of the equation
[tex]\implies 1296 + 225 = (c)^{2}\\[/tex]
[tex]\implies 1521 = (c)^{2}\\[/tex]
Take square root both sides
[tex]\implies \sqrt[2]{1521 } = \sqrt[2]{c^{2} }[/tex]
Solve for "c" by simplifying the roots
[tex]\implies \sqrt[2]{39 \times 39 } = \sqrt[2]{c \times c }[/tex]
[tex]\implies \boxed{39 = c}[/tex]
Thus, the measure of the missing side length (c) is 39 units.

Answers
Answer:
126 square units
Step-by-step explanation:
Area of section 1 is 8 square units which is triangle and,
Area of triangle is = [tex]\frac{1}{2}\times b\times h[/tex]
b= 2 units and height =8 units
So,
Area of section 1 = [tex]\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}[/tex]
Same Area is of section 2 which is also a triangle and has same base and height.
So,
Area of Section 2 = [tex]\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}[/tex]
Now the Area of section 3 which is square with side of 10 units
So,
Area of section 3 = [tex]a^{2} =10\times10=100\quad \text{square units}[/tex]
Total Area of Trapezoid = [tex]8+8+100=126 \quad \text{square units}[/tex]
Mrs. Murray wants to hang lights around the edge of the ceiling. The ceiling measures 14.5 feet by 9.6 feet. What is the perimeter, in feet, of Mrs. Murray's ceiling?
What is the perimeter of the ceiling in inches.
Answers
Answer:
48.2 feet
or
578.4 inches
Step-by-step explanation:
Perimeter is the distance around the shape or in this case the room. Assuming the room is a rectangle you would have two walls of the same length totaling 4 walls.
To find the perimeter add up 14.5 + 14.5 + 9.6 + 9.6 = 48.2 feet
Since it askes for the answer in inches you have to convert from feet to inches by multiplying your answer by twelve.

6) Give all asymptotes
Answers
A curve asymptote is a line where the distance between the curve and the line approaches 0. The function is undefined for the value of x=(5/2). Thus, x=(5/2) is an asymptote.
What are asymptotes?A curve asymptote is a line where the distance between the curve and the line approaches 0 when one or both of the x or y coordinates approaches infinity.
The asymptotes are the values for which the function is not defined. The asymptotes of a fractional function are found by equating its denominator's factors against zero. Therefore, the value of the asymptotes is,
[tex](2x-5)=0\\\\2x=5\\\\x=\dfrac52[/tex]
[tex]x-5=0\\\\x=5[/tex]
Now, substitute the value of x as (5/2) and 5, to know if the function is defined or not.
[tex]f(x) = \dfrac{(7x-1)(x-5)}{(2x-5)(x-5)}\\\\\\f(5) = \dfrac{[7(5)-1](5-5)}{[2(5)-5](5-5)}\\\\\\f(5) = \dfrac{(35-1)(0)}{(10-5)(0)} = 0[/tex]
Since for the value of x=5, the function is defined and returns the value as 0. Thus, x=5 is not an asymptote.
[tex]f(x) = \dfrac{(7x-1)(x-5)}{(2x-5)(x-5)}\\\\\\f(\frac52) = \dfrac{[7(\frac52)-1](\frac52-5)}{[2(\frac52)-5](\frac52-5)}\\\\\\f(\frac52) = \dfrac{(16.5)(-2.5)}{(0)(-2.5)} = \dfrac{\infty}{0}[/tex]
Since the function is undefined for the value of x=(5/2). Thus, x=(5/2) is an asymptote.

What is Binomial distribution?Binomial distribution can be thought of as simply the probability of a SUCCESS or FAILURE outcome in an experiment or survey that is repeated multiple times.
Probability= [tex]C^{n}_r\; p^{r} \;q^{(n-r)[/tex]
where, n= number of trial,
r= number of success desire,
p= probability of success,
q= probability of Failure
probability of success = 0.34
To find the probability of winning exactly 8 hits in next 20 at-bats we find
dbinom (8, 20, 0.34)
Since p= 0.34
q= 1-p
= 1-0.34
= 0.66
n= 20, r=8
Using Binomial Distribution, we get
Probability= [tex]C^{n}_r\; p^{r} \;q^{(n-r)[/tex]
=[tex]\frac{n!}{r!(n-r)!} p^{r}\; q^{(n-r)}[/tex]
= [tex]\frac{20!}{8!(20-8)!} (0.34)^{8}\; (0.66)^{(20-8)}[/tex]
= 125970 x 0.0001785794 x 0.00683168
= 0.1536830
≈ 0.153 (Round off to the nearest thousandth.)

Neither Tom nor Roy sits in the front.
Who sits in the middle, and how old is he? Be sure to check both answers.
Answers
Answer:
Tom sits in the middle and he is 18
Step-by-step explanation:
On the table you will first mark off Tom from being in the rear, as well as being 19
You will mark off Tom and Roy from the 1st, which places Davis as 1st, you also know that Tom is neither 1st nor last, so he is in the middle.
Now you see that Roy is neither in the 1st nor middle, so he is last.
Last is also the 20 yr old, so Roy is 20yrs and last seat.
Tom is neither 19 or 20.
So Tom is in the middle and 18yrs old

1.1 Factoring x2 - x - 2
The first term is, x2 its coefficient is 1 .
The middle term is, -x its coefficient is -1 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 1 • -2 = -2
Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is -1 .
-2 + 1 = -1 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 1
x2 - 2x + 1x - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-2)
Add up the last 2 terms, pulling out common factors :
1 • (x-2)
Step-5 : Add up the four terms of step 4 :
(x+1) • (x-2)
Which is the desired factorization
