Answer:

Protractor

Step-by-step explanation:

A POSTULATE, LAW OR THEORY SHOULD NEVER BE ALTERED

∴ The protractor postulate states that the measurement of an angle between two rays can be designated as a unique number, and this number would be between 0 and 180 degrees, Hence for every angle A, there corresponds a positive real number less than or equal to 180. This postulate guarantee the use of a protractor to measure angles.

Hence, Given line AB and point O on that line in such a way that any ray that can be drawn with its endpoint at O can be put into a one- to-one correspondence with the real numbers between 0 and 180 is a statement that explains Protractor's Postulate.

(X-7)(3x+2) need answer!!
grin007 [14]

Answer: the answer is

=3x^{2}−19x−14  

Step-by-step explanation:  (x−7)(3x+2)

=(x+−7)(3x+2)

=(x)(3x)+(x)(2)+(−7)(3x)+(−7)(2)

=3x2+2x−21x−14

=3x2−19x−14

Given :
pashok25 [27]

\\ \sf\longmapsto A=(1-4)-(2+1)

\\ \sf\longmapsto A=-3-3

\\ \sf\longmapsto A=-6

\\ \sf\longmapsto B=(3-\dfrac{1}{2})-(2-4)

\\ \sf\longmapsto B=\left(\dfrac{5}{2}\right)+2

\\ \sf\longmapsto B=\dfrac{5+4}{2}

\\ \sf\longmapsto B=\dfrac{9}{2}

Now

\\ \sf\longmapsto AB=-6\times \dfrac{9}{2}

\\ \sf\longmapsto AB=-3(9)

\\ \sf\longmapsto AB=-27

BA

\\ \sf\longmapsto \dfrac{9}{2}\times (-6)

\\ \sf\longmapsto 9(-3)

\\ \sf\longmapsto -27

Observed:-

\\ \sf\longmapsto AB=BA
