Q:
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
Accepted Solution
A:
x / 48 = sin(10)
x = 48* .1736
x = 8.3335
rounds to 8.3"Β
sin 1o^0Β = 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
