Answer:
<h3><em>t° = 55°</em></h3>
Step-by-step explanation:
t° + 55° = 90° (Exterior angle of a triangle is equal to the sum of the opposite interior angles.)

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.
