Pls help me with this
Nonamiya [84]

22  True  For all real Numbers A and B,  A  -   B   =    -B   +  A

23  True   For all real Numbers  P, Q, and R, P  -  Q  - R  =  P - R  - Q

24) True For all real Numbers  X, Y, Z and (X   +  Y )  +  Z  =  Z   +  (X  +  Y)

25) False  For all real Numbers M and N,  M/M * N = N/N ==> Example: 5/5  *  3  ≠   3/3  *  5

26) Examples:

Counterexamples =====>   5  - 0  = 5;   5/1   =  5  

5   -  3   ≠  3    -   5;   (5 -  3 )  -    2  ≠   5  -  (3   -  2 );    

6/3    ≠   3/6;   (24/6 )/2   ≠   24/ (6/ 2 )



Hope that helps!!!!                                         : )

Find the measure of the exterior angle.
Illusion [34]

Answer:

<em> 108 degrees</em>

Step-by-step explanation:

From the diagram we are given

Interior angles are 2x + 1 and 63 degrees

Exterior angle = 5x -2

The sum of interior angles is equal to the exterior angle

2x + 1 + 63 = 5x - 2

2x + 64 = 5x - 2

2x - 5x = -2-64

-3x = -66

x = -66/-3

x = 22

Get the exterior angle:

Exterior angle = 5x-2

Exterior angle = 5(22) - 2

Exterior angle = 110-2

Exterior angle  = 108 degrees

<em>Hence the measure of the exterior angle is 108 degrees</em>
