Please I REALY NEED HELPTriangle ABC is similar to triangle LMN by the AA Similarity Postulate.

Also, m∠A = 108° and m∠C = 2(m∠M).

What is m∠M?

_________ °

Answers

since two of the triangles are similar that means they are the same thing : 
<A = <L
108 = 108

<C is twice from <M so :
<C is 2x                 < M is x             


as you note down the answer you can draw two triangles and label them according to thier values,  you will see that triangle ABC has two things now  ;
                                                           a = 108   and   c = 2x
when you have two measures in a triangle you can find the 3rd one :
suppose that third < of  triangle ABC is x ;
108 + 2x + x = 180
108 + 3x = 180
 3x = 180 - 108 
 3x = 72 
  x = 24
                
                                          <m = 24 

further if you want to find C :
                                          < c = 2x 
                                      < c = 2 ( 24 ) 
                                       < c = 48                  
 
                

Kate has gone up to the chalkboard to do math problems 5 more times than Andre. Kate has gone up 11 times. Which equation represents this situation?A- a - 11 = 5

B- 5a = 11

C- a - 5 = 11

D- a + 5 = 11

Answers

it would actually be D. it says 5 MORE times than Andre, not 5 times (as in multiply) Andre.
 B, because it says she has gone up 5 times Andre (a).

450+25s=79+25s yes for algevra

Answers

Answer:

This statement is false

Step-by-step explanation:

To get the 25s on one side, you would need to subtract 25s from both sides but that leaves you with 450 =79 which is not true.

450+25s=79+25s

subtract 25s to both sides:

450=79

this is FALSE

Same as the last one you asked. 

AB + BC = AC. Just think of it like Part + Part = Whole Thing

(2x + 6) + (6x + 5) = 51

Combine like terms:
8x + 11 = 51

Subtract 11 from both sides to get the variable and its coefficient on its own:
8x = 51 - 11
8x = 40

Divide both sides by 8 to isolate the variable:
x = 5

It's asking for us to find BC so now we plug in x = 5 to the equation it gave for BC. 

6x + 5
6(5) + 5
30 + 5
35

BC is 35 units long.
