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.
Answer:
.
Step-by-step explanation:
Given information:
Radius of circle = 8 cm
Area of sector =
Formula for area of sector is
where, r is radius and is central angle in radian.
Substitute and r=8 in the above formula.
Therefore, the measure of the sector in radians is .
