150 feet up
sin 37.0 = 150 / hypotenuse which is the wire
so yes
150/ sin 37.0
you were only given the height to the nearest foot so I would say 249 feet
but what if it were sin 37.1 instead of 37.0
then I would get 248.6
well that is still 249 :)
A smokestack is 180 ft high. A guy wire must be fastened to the stack 30.0 ft from the top. The guy wire makes an angle of 37.0° with the ground. Find the length of the guy wire. Use significant figures.
I did:
180ft - 30ft =150ft
sin 37 = 150/x
x=150/sin 37
x= 249.2460212
how do I the significant figures for my answer: 249.2460212 ?
