The stewardess has a suitcase that measures 26 inches high not including the attached handle, x. I her hand is about 30 inches from the floor with an angle of elevation of 45°, how long is the handle?
Find this by using the definition of sine;
sin(45°)=30/(26 + L) where L is the length of the handle
sin(45°) is 1/√2 so 1/√2 = 30/(26 + L)
Rearrange:
(26 + L)/√2 = 30
26 + L = 30*√2
L = 30*√2 - 26 ≈ 16.4 inches
.
I cannot understand this question at all :/
Melody, this is how I picture the situation
Thanks Alan, I forgot that travel bags have wheels these days.
To me a suitcase is is a much smaller thing with no wheels
I was really confused LOL :)
