Answer:
I think it's
D. AC/GI = BC/HI
Step-by-step explanation:
Angles that are congruent don't necessarily mean they're similar. But this is what I saw that is associated with similarity with triangles.
AC and GI are corresponding sides and BC and HI are corresponding sides as well so, yeah. D.
I think.
I guess.
I don't know.
I didn't pay attention, tbh. LOL

X=90 degrees you can get the answer by adding up all the angles
x = number of 1-cent stamps
y = number of 8-cent stamps
z = number of 12-cent stamps
We have 31 stamps all together, so x+y+z = 31.
"I have 4 more 1-cent stamps than 8-cent stamps" means we have the equation x = y+8. Whatever y is, add 8 to it to get x. Solve for y to get y = x-8.
You also have "twice as many one cent stamps as 12 cent stamps", so x = 2z. Solving for z gets you z = 0.5x
-------------
x+y+z = 31
x+x-8+z = 31 ... y replaced with x-8
x+x-8+0.5x = 31 ... plug in z = 0.5x
2.5x-8 = 31
2.5x = 31+8
2.5x = 39
x = 39/2.5
x = 15.6
Your teacher made a typo somewhere because we should get a positive whole number result for x (since x is a count of how many 1-cent stamps we have).
It has 15 things affghhjj ibhcff
