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:

This is the problem that we need to solve. The best way to get about it is to first:
- Multiply the constant numbers (3 and 17). 3×17 is 51.
- Next multiply the radicals.
- Simplify the squareroot of 108 since it is 49 times 2. It would be equal to 7 squareroots of 2.
- Our final answer would be:
- 51 x 7 is 357, so the answer above is right.
The skills needed are multiplication, mulitplication of radicals, and simplifying radicals, so if you want to review anything use these as reference.
Hope you understood and have a nice day!!
