Answer:

m∠a = 60°

Step-by-step explanation:

Hi there,

Before answering this question, you should know that the sum of all the angles in a triangle will always be 180°. Therefore, we can write this equation to find the value of ∠a :

70° + 50° + m∠a = 180°

Solve for m∠a

120° + m∠a = 180°

m∠a = 60°

Hope this answer helps. Cheers.

MO is twice as long as MN. NO= 36 cm. What lengths must NM be between in order for MNO to be formed?
Nataliya [291]

Answer:

Length of NM is 36 cm

Step-by-step explanation:

Length of MN + Length of NO = Length of MNO (Or only MO)

X + 36 = 2X

2X - X = 36

X = 36 cm

Thus, length of MN is equal to length of NO i.e 36 cm

The line MNO has point N, that bisect it into two equal half.

Thus, the line MNO has two parts

Total length of line MNO = MN + NO = 36 + 36 = 72 cm

What is the sum of 3 consecutive odd integers is -39
trapecia [35]
Answer: The three consecutive odd integers are:  -15, -13, and -11 .
_______________________________________________________
Explanation:
_____________________________________________
  x + (x + 2) + (x + 4) = -39 ;
_____________________________________________
 in which "x" is one of the integers, 
           "(x + 2)" is the next consecutive odd integer;
           "(x + 4)"  is the third consecutive odd integer.
__________________________________________
By solving for "x", we can solve for each of three (3) consecutive odd integers.
________________________________________________________
     x + (x + 2) + (x + 4) = -39  ;
_________________________________________________________
          1x + 1x + 2 + 1x+ 4 = -39 ;
_____________________________________________________  
                   3x + 6 = -39 ;
______________________________________________
               Subtract  "6" from EACH side of the equation:
______________________________________________
                    3x + 6 − 6  =  -39 <span>− 6 ;
____________________________________________________
        to get:   3x = -45 ;
____________________________________________________
           Divide EACH side of the equation by "3" ;
____________________________________________________
                 3x / 3 = -45 / 3 ;
_____________________________________________________
        to get:   x = -15 ;
______________________________________________________
     x + 2 =  -15 + 2 = -13 ;
_______________________________________________________
     x + 4 =  -15 + 4 =  -11 .
___________________________________________________
Are: -15, -13, and -11 ;  Consecutive odd integers?  YES!
___________________________________________________
Does:  -15 + (-13) + (-11)  =? = -39 ??
_____________________________________________________
           -15 </span>− 13 <span>− 11 = ? 39 ??  YES!
____________________________________________________
Answer: The three consecutive odd integers are:  -15, -13, and -11.
