When the lines are parallel and angles are given, and since a straight line is 180°, the 2 angles of the line intersecting the parallel lines have to add up to be 180. Therefore,

Answer:

21. m<2 = 31 degree

22. m<11 = 96 degrees

23. m<5 = 127 degree

24. m<12 = 84 degree

25. m<6 = 53 degree

Step-by-step explanation:

21 explain) m<8 = m<1 = 149 degree b/c Alternate angle rule

                  m<1 + m<2 = 180 b/c straight line is 180 degrees

                  m<2 = 180 - m<1

                  <u><em>m<2 = 180 - 149 = 31 degrees</em></u>

<u><em></em></u>

25 explain) m<3 = <u><em>m<6 = 53</em></u> degree b/c Alternate angle rule

22. explain) m<7 = m<8 - 180 b/c straight line is 180 degrees

                    m<7 = 180-149 = 31

                    m<11 = 180 - m<7 - m<6

                    <u><em>m<11 = 180 -31 -53 = 96 degrees</em></u>

<u><em></em></u>

24. explain) 180 = m<11 + m<12 b/c straight line is 180 degrees

                    180 - m<11 = m<12

                     180 - 96 = m<12

                     <u><em> 84 = m<12</em></u>

<u><em></em></u>

25. explain) m<3 = m<6 = 53 degree b/c Alternate angle rule

                   180 = m<5 + m<6 b/c straight line is 180 degrees

                      180 - m<6 = m<5

                     180 - 53 = m<5

                      <u><em>127 = m<5</em></u>

If Mars has a diameter of approximately 4200 miles, what is the volume of Mars.
Alex777 [14]

Answer:

Dimplified: 3.88×10^{10}, or 38,800,000,000

Unsimplified: 38,792,400,000

Step-by-step explanation:

Remember, the volume of a sphere is V=\frac{4}{3}\pi r^{3}

This comes into: 3.87924×10^{10}

As we know, the shape of mars is a sphere.

Let me know if you have a question, or if it lets you not have the ×10^{10}

The value of the square root of 82 is between which two integers?
zaharov [31]
The answer: 9 and 10 or 8 and 9
8x8=64
9x9=81
10x10=100
They are close by 18 so If it’s only an answer I would go for 8 and 9

Vertical, Complementary and Linear Pair Angles help me please
Mariana [72]
I saw this same type of question and page but with different numbers just 5 minutes ago...

Anyway here’s the answers:
1) Complementary
3x+1+44=90
3x+45=90
3x=45
x=5
2) Vertical
Ignore everything about the work. The answer is 120 degrees because they’re vertical angles.
3) Supplementary
15x-5+110=180
15x+105=180
15x=75
x=5
And I can’t see the last question clearly
