Answer:
Step-by-step explanation:
Rule
The sin of any angle = cos(90 - the angle used for the sine)
Sin(64) = cos(90 - 64)
Sin(64) = cos(26)
Check
Sin(64) = 0.8988
Cos(26) = 0.8988
Answer:
Whole, natural, integer, rational, real

Answer:
6π inches/min
Step-by-step explanation:
he tip of the second hand makes a complete circle in
60 sec, or 1min
The length of this circle is the circumference, C
C=2πr
Given: r=8 in
C= 2π×8 =16π
C= 16π
The linear velocity is 6π/1 = 6π inches/min
