Hi there!
~
cosec 20 -cot 40= 1/sin 20 - cos 40/sin 40
= (sin 40 -cos 40 sin20)/(sin 40 sin 20)
= 1/sin 40 ( 2 cos 20 - cos 40)
=1/sin20 ( 2 cos(60-40)-cos 40)
=1/sin40( 2 cos 60 cos 40 - 2 sin 60 -sin 40-cos 40)
Put the value of cos 60
= 1/sin 40 ( 2 sin 60 sin 40)
=root(3)
Hope this helped you!
Answer:
no possible solution
Step-by-step explanation:
Price of 18 chairs: 18 x 150 = $2700
Minimum number of tables to meet $4800 threshold: (4800 - 2700) ÷ 350 = 6
To reach the $4800 requirement, the store must sell a minimum of 6 tables in addition to the 18 chairs. However, it is stated that the store can ship a maximum of 20 pieces of furniture, and selling 18 chairs and 6 tables would exceed this (18 + 6 = 24), therefore there is no possible solution.
