Answer:
<em>1 unit left and 7 units up</em>
Step-by-step explanation:
|3 - 2| = |1| = 1
The x-coordinate when from 3 to 2, so it is 1 unit left.
|-4 - 3| = |7| = 7
The y-coordinate when from -4 to 3, so it is 7 units up.
Step-by-step explanation:
2(x+4) = 12
or, 2x + 8 = 12
or, 2x = 12-8
or, 2x = 4
or, x = 4÷2
hence, x = 2
The line GH bisects The triangle FGI meaning it divides it into two equal parts <em>(that is the definition if bisection); </em>therefore, the angles FGH and HGI are equal:

Now let us add 2 to both sides gives

subtracting 4x from both sides gives


Hence, x = 11.
The measure of FGH is

(B)
The measure of HGI is

(C)
The measure of FGI is the sum of HGI and FGH:
