Answer:
x=π/2 ,3π/2
Step-by-step explanation:
cot x(csc x+1)=0
either cot x=0
tanx=∞=tan (π/2)
x=π/2
or csc x=-1
or sin x=-1=-sin (π/2)=sin (π+π/2)=sin (3π/2)
x=3π/2
Answer:
6x4=24 for 1 side
24x5=120 for total surface area of I'm not mistaken...
Option A: drop of 8 meters would be correct because a drop in this case indicates something has been removed. -8 equals 8 below 0.
