Answer:
- x = arcsin(√20.5 -3√2) +2kπ . . . k any integer
- x = π - arcsin(√20.5 -3√2) +2kπ . . . k any integer
Step-by-step explanation:
Add √(82) -3sin(x) to both sides to get ...
2sin(x) = √82 -√72
Now, divide by 2 and find the arcsine:
sin(x) = (√82 -√72)/2
x = arcsin((√82 -√72)/2)
Of course, the supplement of this angle is also a solution, along with all the aliases of these angles.
___
In degrees, the solutions are approximately 16.562° and 163.438° and integer multiples of 360° added to these.
Since there's 1 hour and 14 minutes until noon, and one hour is 60 minutes, 60 + 14 = 74 minutes until noon.
Answer:
She has $128.65 left
Step-by-step explanation:
$257.29 x 1/4 = $64.32
$257.29 - $64.32 = $192.97
$192.97 x 1/3 = $64.32
$192.97 - $64.32 = $128.65
