Step-by-step explanation:
after you draw a unit circle you will find the answer
cosec(3pi)=1/sin(3pi)
sin3pi=sinpi=0
so cosec3pi=1/0 which is undefined.
Create and solve an equation of ratios:
10 ft 8 oz
------- = -------
x 48 oz (note that 3 lb = 48 oz)
Then 480 = 8x, and x = 60 ft (answer)
360 degrees. x+y+z = 360°
The 8 full boxes have 80 apples (8x10) and the 6 half boxes have 30 apples (6x5).
So: 80+30=110
