First of all, take your calculator off Radians (RAD) and make sure you are in
degrees (DEG).
(How did you not realize that a negative result from sin 37° would not make any sense?)
All the data given contains 3 digits, so use 3 digits in your answer once to get
the new result.
A smokestack is 190 ft high. A guy wire must be fastened to the stack 20.0 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:
190 - 20 = 170
170/w=sin 37
w=170/sin37
w= -264.16461
the question said used significant figures so my answer is -264.16
is my answer correct?
