From my understanding you ahould use the trig function cos to solve this.
cos(c) = 15/25 or 0.6
if you have this following function on your calculator I suggest using it:
cos ^{ - 1}
by using the function like so:
cos^{ - 1} (0.6
you should get about 53.13° (rounding to the nearest hundredth)
Hope this helped.
Answer:
The power developed by the 1st crane is twice the power developed by the 2nd crane.
Step-by-step explanation:
According to the question,
work done by both of the cranes are the same. Let it be W.
Then power developed by the first crane,
=
unit -----------------(1)
and, the power developed by the 2nd crane,
=
unit ------------------(2)
So, we get that,

So, the power developed by the 1st crane is twice the power developed by the 2nd crane.
