Answer:

7. ○ ∆ACB ≅ ∆DFE

6. ○ $\displaystyle 43°$

5. ○ $\displaystyle ∠M ≅ ∠S$

4. ○ $\displaystyle octagon$

3. ○ $\displaystyle squares$

2. ○ $\displaystyle rhombus$

1. ○ $\displaystyle equilateral\:triangle$

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 octagon has eight sides, a triangle has three sides, a hexagon has six sides, and a pentagon has five sides. With this being stated, you have your answer.

3. In a previous lesson, we confirmed that all squares are rectangles 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.

I am joyous to assist you anytime.

Answer:

1000 years

Step-by-step explanation:

1x10^11 is basically 100 billion

1x10^8 is basically 100 million

so 100 billion divided by 100 milllion is basically 1000

so 1000 years

Find the perimeter of the polygon defined by the coordinates (5, 8), (12, 0), (-5, 0), and (-1, 8). (Round to nearest tenth)

a_sh-v [17]

Based on my created polygon, I formed a trapezoid.

I need to use the Pythagorean theorem to solve for the two sides that are the hypotenuse of the right triangles derived from the image.

1st side: distance from -1 to 5 = 6
2nd side: distance from -5 to 12 = 17
3rd side: hypotenuse:
a = -5 to -1 = 4
b = 0 t0 8 = 8
c² = 4² + 8² = 16 + 64 = 80
c = √80 = 8.94

4th side: hypotenuse:
a = 5 to 12 = 7
b = 0 to 8 = 8
c² = 7² + 8² = 49 + 64 = 113
c = √113 = 10.63

Perimeter = 6 + 17 + 8.94 + 10.63 = 42.57 or 42.6 units.
