Answer: 252 dollars
Step-by-step explanation: the computer is 400$ and 400*0.3 is the 30% off. That makes 120, 400-120 is 280 and then the 10% off, 280*0.1=28. Last step is to do 280-28=252
The distance across the lake, a is 611 yards
<h3>Right angle triangle:</h3>
Right angle triangle have one of its angles as 90 degrees. Therefore, the side a can be found using trigonometric ratios,
Therefore,
tan 47° = opposite / adjacent
tan 47° = a / 570
cross multiply
a = 570 tan 47°
a = 570 × 1.07236871002
a = 611.250164714
a = 611 yards
