Answer:
7. ○ ∆<em>ACB</em> ≅ ∆<em>DFE</em>
6. ○ 
5. ○ 
4. ○ 
3. ○ 
2. ○ 
1. ○ 
Step-by-step explanation:
7. Everything is in correspondence with each other, so just follow the pattern in the order the they were originally.
6. All angles correspond with each other, so just follow the pattern.
5. All segments and angles correspond with each other, so just follow their patterns.
4. An <em>octagon</em><em> </em>has eight sides, a triangle has three sides, a <em>hexagon</em> has six sides, and a <em>pentagon</em><em> </em>has five sides. With this being stated, you have your answer.
3. In a previous lesson, we confirmed that <em>all squares </em><em>are</em><em> </em><em>rectangles</em><em> </em>because it is a quadrilateral with four right angles.
2. This is obviously a rhombus because it is a quadrilateral with four congruent angles and sides.
1. An EQUILATERAL TRIANGLE is a regular polygon because they have three congruent angles and sides.

Answer:
Roster Form of M = {-2, -1 , 0, 1}
Set Builder Form of M = {x : x is an integer and -3 < x ≤ 1 }
Step-by-step explanation:
Roster Form: A set is said to be in roster form if each element of the set is written distinctly in the set with commas in between them.
Set Builder Form: A set is said to be in set builder form if all the set elements are represented by describing their properties.
Now, here M is the set of integers that are greater than -3 and less than or equal to 1.
So, by definition of the set forms,
Roster Form of M = {-2, -1 , 0, 1}
Set Builder Form of M = {x : x is an integer and -3 < x ≤ 1 }
You're equation will look like:
R = 1167 + 1167 + 1167 - 239
To get the answer, simplify
R = 1167 + 1167 + 1167 - 239 = 3262

Answer:
C
Step-by-step explanation:
-2x + 7= 3x -8
+8
-2x + 15=3x
+2x
15=5x
divide
x=3
put 3 in one of the equations
y= 3(3) - 8
y=9-8 = y=1
answer is c

The value of cos(L) in the triangle is Five-thirteenths
<h3>What are right triangles?</h3>
Right triangles are triangles whose one of its angle has a measure of 90 degrees
<h3>How to determine the value of cos(L)?</h3>
The value of a cosine function is calculated as:
cos(L) = Adjacent/Hypotenuse
The hypotenuse is calculated as
Hypotenuse^2 = Opposite^2 + Adjacent^2
So, we have:
Hypotenuse^2 = 12^2 + 5^2
Evaluate
Hypotenuse^2 = 169
Take the square root of both sides
Hypotenuse = 13
So, we have
Adjacent = 5
Hypotenuse = 13
Recall that
cos(L) = Adjacent/Hypotenuse
This gives
cos(L) = 5/13
Hence, the value of cos(L) in the triangle is Five-thirteenths
