Select TWO equations that represent angle relationships in the figure. A 7x−9=6x+14 B 7x−9=5x−10+33 C 6x+14=33+180−(7x−9) D 33+(
Diano4ka-milaya [45]

The value of x from the figure is 1 and the equations that represent angle relationships in the figure are 7x + 5x = 3 + 9 and 12x = 12

<h3>Lines and angles</h3>

The point where two lines meet is known as an angle. From the given diagram;

7x-9 = 5x + 3

Determine the value of x

7x + 5x = 3 + 9
12x = 12
x = 12/12

x = 1

Hence the value of x from the figure is 1 and the equations that represent angle relationships in the figure are 7x + 5x = 3 + 9 and 12x = 12

Find the absolute value of 1 and - 1
AlekseyPX
The absolute value of BOTH of those numbers is ' 1 '.

Oh !  Wait just a second.  Did you mean for the  1  and the  -1  to be combined
in some way  ?  If that's what you had in mind,  then you'll have to be more
specific.   "And" is no mathematical operation that I know of.
