Answer:
Minimum length of rope needed to span the sides of the prism is 10 units.
Step-by-step explanation:
Let us draw a perpendicular from apex to base BC,Let it be AD since ΔABC is isosceles triangle, that perpendicular will touch mid of base. That is BD=DC=
=3
Now we know the angle m∠ABC as 53.13°.
From ΔADC, 
≈10
Hence minimum length of rope needed to span the sides of prism is 10 units.

Answer:
16 workers are required to complete the work in 45 days...
Step-by-step explanation:
12 workers are required to complete the work in 60 days
so... 60*12=720 workers are required to complete the work in 1 day
Hence,
720/45 = 16 workers are required to complete the work in 45 days.
The complete question in the attached figure
we know that
<span>An<span> exterior angle</span></span><span> is one that has its vertex at an outer point of the circumference.
</span><span>The measure of the external angle is the semi-difference of the arcs that it covers.
in this problem the external angle is </span>∡(9x-5)°
and
the semi-difference of the arcs that it covers is (1/2)*(158°-64°)=47°
then
(9x-5)=47-------> 9x=47+5----------> 9x=52--------> x=5.78°
the answer is
x=5.78°
