Answer: Choice A) AA postulate; 18
---------------------------------------------------------------------------------------
Work Shown:
The triangles are similar to each other due to the AA (angle angle) postulate. The top angles are overlapping or shared angles. So that's the first pair. The second pair of angles is either bottom pair of angles, from the fact that corresponding angles are congruent. This is only true if the lines are parallel.
Due to the similar triangles, we can set up the proportion and solve for x
8/(8+4) = 12/x
8/12 = 12/x
8*x = 12*12 ... cross multiply
8x = 144
x = 144/8
x = 18
The answer is $132,000
First you multiply 120,000 by .10 which you get 12,000
Then you just add it and you find the answer
3 and 17
17-3=14
hope that helps
