Answer:
The length of rope is 20.0 ft . Hence, <u>option (1) </u> is correct.
Step-by-step explanation:
In the figure below AB represents pole having height 10 ft and AC represents the rope that is from the top of pole to the ground. BC represent the ground distance from base of tower to the rope.
The rope and the ground form a 30 degree angle that is the angle between BC and AC is 30°.
In right angled triangle ABC with right angle at B.
Since we have to find the length of rope that is the value of side AC.
Using trigonometric ratios


Putting values,

We know, 

On solving we get,
AC= 20.0 ft
Thus, the length of rope is 20.0 ft
Hence, <u>option (1)</u> is correct.
Answer:
15
Step-by-step explanation:
38/2.5=15.2
Round it to 15
I think it would be irrational but I might be wrong I’m not a expert well I am but I sorta don’t get it
What exactly are you asking?
Multiply your length value by 2.54. One inch is equal to roughly 2.54 centimeters,
Its 20.32 cm btw.
