Hello, can anyone help me by answering all these? Please
kompoz [17]

Answer: See step by step

Step-by-step explanation: For A my 15 statements are.

  1. It has 3 triangles inside it, ACD, ADC, and ABC
  2. It has 2 right triangles, and 1 isoceles
  3. AC≅AB
  4. CD≅DB
  5. D is midpoint of CB
  6. AD⊥CB
  7. Angle CDA=90 degrees
  8. Angle  BDA equal 90 degrees
  9. AD≅AD
  10. ΔCDA≅ΔBDA by any congruence theorem, (SSS, SSA,AAS,ASA, HL)
  11. AD^{2}+ DB^{2}=AB^{2}

 12.AD^{2}+ CD^{2}= AC^{2}

   13. Triangle ABC has a max of 180 degrees.

     14. We can rotate this triangle 180 degrees and it will coincide.

       15. We can reflect triangle ACD over vertical line ACD and it will be congruent to ABD.

 2.  We use pythagorean theorem since it has a right angle.

      AD^{2}+ DB^{2}=AB^{2} Let plug it in.

      40^{2}+b^{2}=45^{2}

        1600+ b^2=2025

      b^2=424

      sqr root of 425 is about 21. Now let find the perimeter.

      AB is 45, Since BD+DC=CB, and they are congruent they are equal so 21+21=42 and AC is congruent to AB so it is 45. So the perimeter is  132.

  For 3. Start at the orgin, then go up 5 on the y-axis so you should be at (0,5)

   Then use the rise over run method to graph it. go left -3 and and up 1. Keep doing that 2 more times then draw a straight line.  

Your 3 point should be

(0,5)

(1,2)

(2,1)

For brainliest please help!
Advocard [28]

Answer:

negative multiples of 3 less than -3

Step-by-step explanation:

if m <9, then

m ={8,7,6,5,4,3,2,1,0,-1,-2,....,..........}

And |6m-55|

So is said that,

when, m= 8

6(8)-55=-6

when, m=7

6(7)-54=-12

when, m = 6

6(6)-54=-18

Since the trend is negative multiples of 3 less than -3

this is my answer
