Triangle A'B'C'is the result of reflecting triangle ABC across the line l
Choose all answers that apply
a. BC and B'C' are both perpendicular to the y-axis
b. <B and <B' have the same measures
c. The perimeters of ABC and A'B'C' are the same
D. None of the above
9514 1404 393
Answer:
b, c
Step-by-step explanation:
Reflection across a line is a "rigid" transformation, so linear measures and angle measures remain unchanged. (b and c are true statements)
Reflection across a line skew to the y-axis will mean that any segment originally perpendicular to the y-axis will not be after the reflection. ('a' is not a true statement)

A woman had $200. She went to a meatshop,
a bookstore and a drugstore. She spent four
times as much money at the meatshop as she
did at the drugstore. She spent $15 less at the
bookstore than at the drugstore. She then had
$5 left.
(a) Using $x to represent the amount she spent
at the drugstore, express in algebraic terms
(i) the amount she spent at the meatshop
(ii) the amount she spent at the bookshop
(b) Obtain an equation for the total amount
of money spent and hence calculate the
amount she spent at the drugstore.

Which angle measure must equal 52°?
A. а
в. Ь
с. с
D. d
Е. е
Answer:
Option C will be your answer
Step-by-step explanation:
Angle C will be equal to 52 by vertical angle theorem
hope it helps you
have a great day !!
Angle c is the vertical opposite angle with 52° so it will have a measure of 52° thus option (C) is correct.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
Two opposite angle made by two intersecting lines is said to be vertically opposite angle so the angle opposite to 52° is c so, ∠c = 52°.
Hence " Angle c has a measure of 52° since it is the vertical opposite angle with 52°".

Find the indicated limit, if it exists.
Answer:
The limit is 1.
Step-by-step explanation:
In this kind of problem, we can use the left and right-hand limit method.
Basically, we need to find the limit by the left side and then by the right side. If both of them are equal the limit does exist if not the limit does not exist.
Left hand
[tex]lim_{-8^{-}}(f(x))=lim_{-8^{-}}(x+9)=-8+9=1[/tex]
Right hand
[tex]lim_{-8^{+}}(f(x))=lim_{-8^{+}}(-7-x)=-7-(-8)=1[/tex]
As we see, both limits are the same, so the limit is equal to 1.
I hope it helps you!
Complete the proof.
Given:
R↔S tangent to circle A and circle B at points R and S.
Prove:
AR ∥ BS
The proof is shown below:
What is tangent?The tangent is defined as a line touching circles or an ellipse at only one point.
As, tangent line is perpendicular to radius of the circle.
So,
AR ⊥ RS
BS ⊥ RS
Thus, AR and BS ⊥ to same line RS.
Now, either AR or BS are in same line or parallel.
since, they are the radius of different circles.
Hence, AR ║BS.

What is the area of the polygon given below?
A. 55 square units
B. 186 square units
C. 131 square units
D. 66 square units
Answer:
○ B. [tex]\displaystyle 186\:square\:units[/tex]
Explanation:
All edges conjoin to form right angles, therefore you have these:
[tex]\displaystyle \boxed{186} \hookrightarrow 121 + 30 + 35 \Rightarrow 11^2 + 5 \times 6 + 5 \times 7[/tex]
OR
[tex]\displaystyle \boxed{186} \hookrightarrow 120 + 66 \Rightarrow 24 \times 5 + 6 \times 11[/tex]

two adjacent angles from a right angle. the larger angle is 3 times the measurement of the smaller angle which is the measurement of the angle?
45°
22.5°
67.5°
30°
Answer:
Because two adjacent angles from a right angle sums up to 90° and the larger angle is 3 times the measurement of the smaller angle, the equation would be 3a + a = 90° (A will be the substituting variable for the smaller angle). Add the like terms to get 4a=90. Divide 4 on both sides to get 22.5°. Substitute 22.5 into the variable, a, to get 67.5. This means that the larger angle would be 67.5° and the smaller angle would be 22.5°.

Answer:
m>z=85
x = 15!
Step-by-step explanation:
85=z because they are opposite eachother and the two lines intersect.
85*2=170, so we have 170 degrees for the two angles we know the measure of. Now, we need to find the remaining angles.
360-17=190. There is 190 degrees that need to be solved still.
190/2 is 95. Each angle remaining is 95 degrees.
8x-25=95
+25
8x = 120

x=15
how do i see if 5 + 3 x -2 and x + 2 (x + 1) + 1 are equivalent or not?
Simplify both of the expressions and see if they are the same
5+3x-2

x+2(x+1)
=x+2x+2
=2+3x
They are not equivalent.
What is the value of X and Y?
9514 1404 393
Answer:
x = 20
y = 70
Step-by-step explanation:
The exterior angle marked 40° is the sum of the remote interior angles in the isosceles triangle at lower right, both of which are x°.
40° = 2x°
x = 20 . . . . . divide by 2°
The angle marked y° is the complement of the one marked x°.
y = 90 -x = 90 -20
y = 70

Heather is considering purchasing an item that costs $17. The sales tax in Heather's area is set at 7.5%. What is the total purchase price that leather would be charged on this purchase? Round your answer to the nearest cent, if necessary.
Answer:
$18.28
Step-by-step explanation:
To get the answer all I did was take 7.5% of 17 which is 1.275
I then rounded 1.275 to 1.28. When you round up the number after the 7 has to be 5 or above. Seeing as the number was 5 we rounded it up to 1.28.
Then I took $17+$1.28= $18.28.
I hope this helps!!!
