Solve the following equations for 0 ≤ theta ≤ 360º cosec(2 — 45°) = 2​
lions [1.4K]

Step-by-step explanation:

here ,

cosec \alpha  =  \frac{1}{ \sin( \alpha ) }

now,

cosec(2-45°)=2

or,

1/sin(2-45°) =2

or,

1/sin2cos45°-cos2sin45=2

or,

\frac{1}{ \sin(2)   \frac{1}{2}   -  \cos(2) \frac{1}{2}  }  = 2

or,

sorry I have that much qualifications to work on this question and hoping this much will make bit easy for you to solve it further

At a grocery store, an uncooked beef roast is on sale for $4.99/lb. At the same store, prepared roast beef is at the deli for $2
Mrrafil [7]
For us to find out how many times more expensive is the deli roast compared to the uncooked roast we need to change the units;
cost of 100g=0.221lb is $2.99
cost of 1 lb will therefore be:
1/0.221*2.99
=$13.53/lb
therefore the number of times more expensive the deli roast is compared to uncooked roast is:
[price of 1lb roasted meat]/[price of 1 lb uncooked meat]
=13.53/4.99
=2.7 times
