Answer:
17
Step-by-step explanation:
We have two congruent triangles here. Thus, b must be 17.
I multiply 1200 times 5 and yet 6000 because it says what is the height
The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.
For example, 80% of 100 = $80. The price would be $180.
Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.
25% of 100 is not the same as 25% of 180.
