Answer:
Write the equation as n + 31 = 113 and subtract 31 from both sides. The answer is 82.
Step-by-step explanation:
The sum of a number and 31 would be 'n + 31'. The sum equaling 113 would be '= 113'.
You would get 'n' by subtracting 31 for each side.
The statement: "Write the equation as n + 31 = 113 and subtract 31 from both sides. The answer is 82." should be the correct answer.
Given :
An equation, 2cos ß sin ß = cos ß .
To Find :
The value for above equation in (0, 2π ] .
Solution :
Now, 2cos ß sin ß = cos ß
2 sin ß = 1
sin ß = 1/2
We know, sin ß = sin (π/6) or sin ß = sin (5π/6) in ( 0, 2π ] .
Therefore,
Hence, this is the required solution.
