Answer:
H=22.5 in
The answer is A
Step-by-step explanation:
Sin(60)=h/26 where h is the height we are interested in
Multiply both side by 26
26*Sin(60) = H
H=22.5 in
the answer is A
Answer:
14 elliptical machines
Step-by-step explanation:
t = # of treadmills
e = # of elliptical machines
t + e = 38
t = e + 10
Substitute:
e + 10 + e = 38
2e = 28
e = 14
Answer:
Third option.
Step-by-step explanation:
You need to remember that the formula used to calculate the arc lenght is:

Where "r" is the radius and "C" is the central angle in radians.
You need to solve for "C":
You know the radius and the arc lenght, therefore, you can substitute values to calculate the central angle in radians. Therefore, this is:
