a doctor is using a treadmill to assess the strength of a patients heart. he sets the 48 inch long treadmill at an incline of 10 degrees. how high is the treadmill raised

x / 48 = sin(10)

x = 48* .1736

x = 8.3335

rounds to 8.3" 




sin 1o^0  = h/48

h = 48 sin 10^0

so; h = 8.3 inches; or

8.3 in.



say you have a triangle:

outside = 48

outside = h

inside = 10^0
